Occasionally in times past I've had time to develop some offbeat Mac software. The samples here are distributed free of charge. Permission to re-distribute, in the original form with no modifications is granted.
Based on a Scientific American
"Computer Recreations" column of years ago, Wallpaper for the
Mind generates chaotic patterns at incredible speed. It's similar to a standard
screensaver on SGI workstations, but runs much faster.
The application is a fat binary, and should run on any Mac running 7.0 or later.

Based on Gerard Holzmann's book, "Beyond Photography",
Pico is a system for manipulating images with mathematical expressions.
A simple expression in Pico can produce very dramatic image effects. Expressions
in Pico are translated on the fly into efficient machine code via a custom
compiler. Pico should run on any Mac with Color QuickDraw and System 7.0
or later. The package includes some sample images and a brief tutorial.
