DoodleTron (a L-system Iterator)

The DoodleTron is a site for exploring simple L-systems. The program starts with the image generated by a simple recursive drawing function surrounded by images which vary a tiny bit. Click on one of the variations, and it moves to the center, surrounded by variations on it. Repeat this 10 to 20 times and novel shapes appear.

Hydroponic gardening

Biomorph is a fun game. You start with a simple drawing, and click on drawings which vary a tiny bit. Repeat this 10 to 20 times, and cool things start to appear.

I've put my books into a database to keep track of them. I used one of those nifty free CueCat barcode scanners and wrote some software based on Cat-A-Log (link has gone dead) to look up the book from the scanned in ISBN in a group of online search engines. The best part is that for about 1/4 of the books I was able to find a cover image.

You can have a look at my books here.

I've read most of them... :).
