"Geodesic Cuboctahedron 7 frequency," by Magnus Wenninger (Saint Johnâ€™s Abbey, Collegeville, MN)Papercraft, 12 inches in diameter, 2009. "Geodesic domes are well known as architectural structures, but generally they exhibit only triangular grids. My main interest, however, has been in having geometric patterns projected onto a spherical surface. The icosahedron is most frequently used for this purpose, but other polyhedrons can serve just as well for the same purpose. 'Geodesic Cuboctahedron 7 frequency' is the cuboctahedron in a 7 frequency basket weave pattern with 6 squares of one color and 12 rectangles of 6 other colors projected onto the surface of the cuboctahedronâ€™s circumsphere." More information about the techniques I use to produce my artistic patterns on a spherical surface can be found in the Dover publication of my book Spherical Models (1999), originally the Cambridge University Press publication of Spherical Models (1979). Robert Webbâ€™s Stella program is now my computer program par excellence.  Magnus Wenninger (Saint Johnâ€™s Abbey, Collegeville, MN) http://www.saintjohnsabbey.org/wenninger/

"Meditations on f(x,y)= (x^2)/2 + xy/2 â€“ (y^4)/8," by Richard Werner (Santa Rosa Junior College, Santa Rosa, CA)2010 Mathematical Art Exhibition Third Prize.
Plastic and wood, two pieces, each 6â€ťx7â€ťx7â€ť, 1998. The two pieces give alternate views of the same threedimensional surface. The sculpture has been used for classroom illustrations of the concept of partial derivatives as well as integration of functions of two variables. Since the construction is with clear plastic, a myriad of delightful views of intersecting curves can be found allowing the viewer to hypersee the surface. "I have been a recreational wood worker and sculptor for much of my life. As a mathematics teacher, I have always been captivated by the beauty of the subject and have wanted to enhance the visual concepts in whatever way I can. The two activities were destined to meet. The first mathematical art that I made was intended mainly for classroom demonstrations. The response was very positive and I began to branch out. New materials, especially metal, have captured my interest. The work that I do now is becoming a blend of my interest in math and my love of nature, with a little bit of steampunk influence creeping in as well."

"Julia's Loops," by Jennifer Ziebarth (California College of the Arts, Oakland, CA)Digital print, 16" x 13", 2009. This fractal image is based on a Julia set, visible in dark blue along the intersections of the loops. The loops, which all begin and end on the Julia set, also exhibit selfsimilarity, and hint at the existence of more small loops hidden behind the larger loops. "I have always been fascinated with repetition, abstraction, and the search for pattern, and this is what drew me to mathematics. As a mathematical artist, this love of repetition and detail has lead me to fractal art. As a mathematician teaching at an art college, some of my work is pedagogical in the sense of illustrating mathematical concepts in aesthetically pleasing ways; some of it is purely visual play."

"Ribbons of Rhythm," by Paul Stacy (Landscape Architect, Sydney, Australia)Giclee digital print, 22" x 14" , 2009. Ribbons of Rhythm (foreground image with detail behind) is an exploration of the aesthetic qualities of Penrose tiling. David Austin in "Penrose Tilings Tied up in Ribbons", describes the ribbons thus: "Opposite sides of a rhomb are parallel to one another. Therefore, if we begin with a rhomb and a pair of opposite sides, we may form a "ribbon" by adding the rhombs attached to that pair of opposite sides and then continuing outward". The print reveals only a single family of parallel ribbons in one orientation, however there are another four orientations associated with a fivefold Penrose tiling. "Without a programming or mathematical background, I explore my interest in Penrose tiles by hand building patterns in Corel Draw and experimenting with colors, shapes, welding, contouring and other functions that allow me to explore the aesthetic realm of Penrose tiling, which continues to hold my interest particularly as long range positional order and beauty are revealed."

"Experiment in Shading," by Norton Starr (Amherst College, Amherst, MA)(Pressurized) ball point pen on paper, 14.25â€ť wide by 15.25â€ť high, 1973. This was drawn by computercontrolled pen on a CalComp Drum plotter at the University of Waterloo. It consists of several hundred concentric star images, with their â€śradiusâ€ť varied sinusoidally so as to create the shadow effects of darker and lighter regions. The end result is like an unrealistically precise charcoal drawing. "As I grew up, my freehand drawing often involved families of parallel lines and curves suggesting shading effects. In 1972 I recognized that with the aid of a computer driven plotter I could obtain pictures essentially impossible by other means. Although I produced a number of drawings of different kinds, I spent a fair amount of time and effort trying to achieve shading effects by drawing lines and curves variably spaced from one another. The computer afforded a degree of control that made possible my use math functions to provide desired transitions between dark and light regions. 'Experiment in Shading' is one consequence of that initiative."  Norton Starr (Amherst College, Amherst, MA) http://www3.amherst.edu/~nstarr/

"Tying and untying," by Victor Stipsic (Washington DC), Marko Vujic (Washington DC), Radmila Sazdanovic Movie Clip, 2009. "Tying and untying" is a short movie addressing one of the principal questions in knot theoryunknotting and distinguishing knots. More precisely, we illustrate John H. Conwayâ€™s classification of knots into knot and link families. Mathematical ideas permeate vivid animations and music creating visualacoustic symphony.

"Perspective Sphere," by Dick A. Termes (Artist, Spearfish, SD)Acrylics on Polyethylene sphere, 10" diameter sphere, 2008. The "Perspective Sphere" is the story of perspective. It shows a 360 degrees in all directions cityscape which is organized with a six point perspective system. This means, every line drawn on the sphere makes a greater circle and every cubical building projects to all six vanishing points which are equally spread around the sphere. This piece also shows examples within the spherical painting of a one point perspective, a two, three, four, five and six point perspective. All are sectioned off with the use of color. "I paint what are called Termespheres. These are inside out total worlds that are painted on spheres that hang and rotate from ceiling motors. These spherical paintings show you up, down and all around environments. Some are interiors of famous buildings and some are outside scene, some are also geometric studies and others are subconscious worlds that I imagine are around me. Most of these explore a six point perspective system which I find to be more true than any of the other systems of perspective. This is my 40th year of exploring work like this on the spherical canvas. I feel this exploration has opened up a new way to see the world and its geometry tells me it is more than just art. I think it connects with math very well."  Dick A. Termes (Artist, Spearfish, SD) www.termespheres.com

"Icosahedron #1," by Briony Thomas (School of Design, University of Leeds, UK)Lasercut acrylic, 6.5" x 5.5" x 6", 2007. The successful application of a pattern to repeat across the faces of a polyhedron is determined by the pattern's underlying lattice structure and its inherent symmetry operations. Only pattern classes containing sixfold rotation are applicable to patterning icosahedron. Icosahedron #1 exhibits a p6 pattern cut from the faces of the solid. Centres of sixfold rotation in the pattern become axes of fivefold rotation at each vertex and all other rotational symmetries are preserved. "As a designer, with a background in textiles, I am fascinated by the fundamental concept of symmetry and its application in the creation of patterns. This recent work explores the possibilities of patterns repeating in threedimensions, around the faces of mathematical solids."  Briony Thomas (School of Design, University of Leeds, UK)

"Solar System," by Eve Torrence (RandolphMacon College, Ashland, VA)Watercolor on paper, 8.5'' x 8.5'' x 8.5", 2009. This polyhedron is comprised of ten tetrahedra. Two mirrorimage compounds of five tetrahedra are merged to form the solid. When the polyhedron is rendered in a single color it is difficult to distinguish the individual tetrahedra, in part because some pairs of faces are coplanar. To help the viewer resolve this visual puzzle, the ten tetrahedra have been painted with distinct patterns and colors, which are suggestive of the Sun and the nine planets. The overall starlike quality of the polyhedron, and the tight entwining of the tetrahedral "planets", is evocative of our solar system. "I love the symmetric beauty of polyhedra and enjoy using paper to create models to study. Through the process of creating a model I am able to truly understand its structure. My own curiosity about the underlying structure of this compound of ten tetrahedra led me to make a multicolored model. I was inspired by the 2009 exhibit 'Images of the Universe from Antiquity to the Telescope' celebrating the 400th anniversary of Galileo's discovery of our moon's craters. This model pays homage to Renaissance depictions of the solar system that used various polyhedra to model the celestial bodies."  Eve Torrence (RandolphMacon College, Ashland, VA)

"Fermat Point," by Suman Vaze (King George V School, Hong Kong)Acrylic on canvas, 20â€ť x 24â€ť, 2008. The Fermat Point of a triangle is the point of least total distance from the vertices of a given triangle. The painting depicts that the Fermat Point of a triangle can be obtained by constructing equilateral triangles on each side and then joining the vertices of the original triangle and the equilateral triangles. It also shows that circles with the sides of the triangle as chords also intersect at the Fermat Point. "I seek to depict interesting mathematical truths, curiosities and puzzles in simple, visually descriptive ways. Mathematical amusements inspire the color and form in my paintings, and I try to strike a balance between the simplicity of the concepts and their depiction in art. The logic and balance of the discipline is beautiful, and I like art that both stills and stimulates the mindthese are the qualities I strive to capture in my work."

"You and me, and an army of monkeys," by Samuel Verbiese (Artist, Overijse, Belgium)Computer image printout glued on cartonboard panel (vZome program by Scott Vorthmann), 17x12 inches (A3, 420x297 mm), 2009 (2005 for the concept of the Golden Pyramid, shown at Bridges London). My 'Golden Pyramid' is a truss that can project (when viewed from underneath, at a precise, quite near point, orthogonally to the back golden triangular face) into the K5 graph (pentagram inscribed in a pentagon) with remarkable proportions (two equilateral and two golden triangles on a golden rectangular base featuring its two diagonals). The spacecraft looking model shown has its struts built here, kind of fractally, from 463 overlapping tiny golden pyramids (that can be 3Dcopied). Thanks to a most welcome serendipity, the chosen view angle gives the attentive viewer the needed substance to the title of this ludical work: on the almost vertical strut in the center of the image where it crosses two other struts, two bearded 'wise' men appear sorry for the ladies : the serendipity unfortunately didn't help them here !  and on the remaining part of that strut, a series of monkey faces... "Besides expressionistic painting and sculpting of the figure and portrait, I am recurrently drawn into geometric projects, probably by previous life."  Samuel Verbiese (Artist, Overijse, Belgium)

"RUBIK's new clothes," by Anna Viragvolgyi (Mathematician, Budapest, Hungary)Stirol cube with plastic foil, 2,5"x2,5"x2,5", 2009. Example of extending pattern of "48 different squares" over the surface of RUBIK's 4x4x4. Each square of the set appears twice on the 96 tiles of the cube. There are various symmetries on the sides of the cube and between the sides also. So there is more than one coherent and continuous arrangement. "I deal with diagonally striped, coloured squares. [These squares assign a restricted de Bruijn sequence S(k,n). There are [k(k1)^(n1)]/2 distinct squares, where k is the number of colours, n is the number of stripes.] Last year I studied the geometric shape of arrangements of the squares [in case of k=3, n=6, S(3,6)=48] with coherent pattern on the plane. Presently my aim is filling surfaces of solid figures with these squares. Here is one of them."  Anna Viragvolgyi (Mathematician, Budapest, Hungary) viragvolgyi.anna@gmail.com

"The Three Gates," by Benjamin Wells (University of San Francisco, CA)Inkjet on transparencies, mounted on acrylic layers in an acrylic frame hung by a laced beadchain, 11" x 9", hung by a beadchain, plus 11"x7" explanatory placard 2009 (updated from 2002). Symbols from logic map a classical aphorism about watching one's tongue into a visually recursive statement. In addition, the colors of red and green play on the binary nature of electronic gates. An accompanying placard gives the aphorism and lists the symbols used. "The art offered is a melding of symbolism from science and mysticism. The flexibility of computeraided design and execution supports this blend of ancient and modern expression. I used to think in threes because my name ends in III. (For more about small numbers, see Michael Schneiderâ€™s 'Constructing the Universe.') Although I am now partial to 8, 17, 36, 1111, and 10^10, I wholly support only 1 alone. But three things can start a sequence, give a contrast or equivalence, or triangulate. Here they pose visual riddle. Math is fun, and art can help make that clear. When it can also take a supportive, spiritual, inspirational, cooperative color, then it is a harbinger of a new humanity. I hope to make art that way."

"K12 embedded in Genus 6," by Carlo Sequin (University of California, Berkeley)Plaster model, hand painted, 5" tall, 2004. The complete graph K12 connects 12 vertices with 66 lines. Of course, in the plane this graph cannot be drawn without many crossings. A surface needs to be at least of genus 6 to allow a crossingfree embedding. With this model I have attempted to find the embedding of highest possible symmetry. The model has the 12fold symmetry of the oriented tetrahedron. The 44 countries bounded by the 66 lines, and colored differently, are all 3sided. "My professional work in computer graphics and geometric design has also provided a bridge to the world of art. In 1994 I started to collaborate with Brent Collins, a wood sculptor, who has been creating abstract geometrical art since the early 1980s. Our teamwork has resulted in a program called â€śSculpture Generator 1â€ť which allows me to explore many more complex ideas inspired by Collinsâ€™ work, and to design and execute such geometries with higher precision. Since 1994, I have constructed several computeraided tools that allow me to explore and expand upon many great inspirations that I have received from several other artists. It also has resulted in many beautiful mathematical models that I have built for my classes at UC Berkeley, often using the latest computerdriven, layeredmanufacturing machines. My profession and my hobby interests merge seamlessly when I explore ever new realms of 'Artistic Geometry'."  Carlo Sequin (University of California, Berkeley) http://www.cs.berkeley.edu

"Spirals in Chaos  The Dance in Four Movements: Design Drawing 1," by Mickey Shaw (Artist, Le Roy, KS)Design drawing (not computer generated ), 21" x 22" ( framed ), 2009. Spirals are curves emanating from central points, progressively growing further away as they revolve around the point. These drawings are unique, one of a kind renditions of spirals, but created in reverse direction from outer edges into a central point. Some variations resembling Sinusoidal, Archimedean and Hyperbolic spirals and even an occasional pseudospheres are created. Drawings are created on a weighted drawing board suspended from a pole with an attached arm holding a pen. The board is set in motion by hand. Drawings are manipulated by changing the motion of the drawing board. Finished drawings are scanned and printed. "My inspirations are drawn from nature, mathematics and science. These inspirations are combined with my own experiences and emotions creating a marriage between what is seen, what is known and what is felt internally. My goal, as artist, is to create for the viewer, visually, the concept that art, mathematics and science display a fundamental connection conveying the idea that all three encompass more than what can just be seen. I believe that art is an intrinsic aspect of all visual experiences and mathematics can provide a basis for understanding and recreating those same experiences. The spiral design drawings convey a twodimensional visualization and exploration of this interconnection."  Mickey Shaw (Artist, Le Roy, KS) http://FullLunaCreations.etsy.com/
