An implementation of Blowfish in Javascript.

A small applet to demonstrate Clifford rotations of wireframe objects.

Consider an image sequence as a rectangular prism. View it through a four-dimensional kaleidoscope and you will have complex reflections in space-time. Here is the Kaleidochron.

54321 is five games in four-, three-, and two-dimensions for one player.

The Geometric or Clifford algebras have a variety of applications in physics and computer vision and other places. Here are C++ template classes which implement Geometric Algebras.

Nearly every raytracer in the world is tied to three dimensions. We know of one that is tied to four dimensions. We suspect there may be some tied to two dimensions. But, this raytracer, true to our mission, allows any number of dimensions.

A paper and a simulator for a distributed array of radio telescopes.

Some little utilities for generating random music..

This is the start of a Java applet which displays line-drawings of four-dimensional cubes and simplexes with the hidden facets removed.
