this screen saver draws two interlocked recursive tetrahedrons. each recursive tetrahedron contains four smaller recursive tetrahedrons at its edges. the relative size, distance and rotation of the descendants changes according to a sine function, the parameters of which can be set interactively. the standalone application can be used to control the settings for the screen saver.

in order to enhance performance, i rewrote the core routines, using display lists aggressively [the recursive structure basically demanded such an approach]. unfortunately, a recursion depth of six or more still looks like a slide show on my 666 MHz powerbook. the outline effect was accomplished by a neat little trick which involves disabling the zbuffer and drawing each tetrahedron four times more.
