Toothpick Sequences

This is a cool applet that allows you to explore various fractal “toothpick sequences”:

A number of options allow the user to look at variants of the object, zoom in, change iteration parameters, and change the underlying sequence.  Click the Introduction button for a short overview.

Not sure what ATT Research plans to do with this, but it’s fun to play around with!
