Another old linky from an unrealized project.

I spent a semester trying to flesh out a 3D adaptation of Flatland in Brown's immersive virtual reality Cave. One of the more delightful web pages we looked at was T. Banchoff and D. Cervone's Surfaces Beyond the Third Dimension. Lots of excellent 4D in 3D/2D illustrations, animations, and interactive applets. The torus looping in on itself is... excellent.

Other projects in the Cave: Cave Painting and Screen.
