There are two Java-based interactive versions of the object that is at the center of the poster. Each of them requires you to have a Java-capable browser, and to have Java enabled. See the documentation for your browser to see how to enable Java.[an error occurred while processing this directive]
Interactive applets and instructions for them are available for:
A version of the central cone that uses the LiveGraphics3D applet and the Mathematica data that was used to print the image that appears in the printed poster. The applet lets you rotate the cone to view it from any angle. Instructions are included on the page linked to the image at the left.
A version of the central cone using a parametric-graphics applet developed at Brown University. The applet can let you change the parameters of the equations and see the results. Instructions are included on the page linked to the image on the left.
