A very old application written in python, it creates patterns by joining dots inscribed around a circle. A rathe minimal version of the spirograph. The image is an animation of the first 29 complete graphs, starting at 3.
Python Source Code
Before html 5 I didn't know of any way to create patterns interactively so I wrote these python routines to create patterns and render them as bitmaps. They are still available to download, though they are written in Python 2.6.
These applets were written years ago, Java has moved on so much since then they no longer work.
