Here are a few things I've whipped up in my spare time. I keep meaning to update this with some newer things... some day...

MtG Arena A web app to run Magic: The Gathering tournaments, using the Google Web Toolkit.
Spinning Illusion A demo of an interesting optical illusion. You can play with the parameters and try to figure out what makes it work.
Spirograph A Spirograph generator written in Java. This was the first Java program I wrote, back when the language was brand new. I am actually amazed that it still works.
Trirograph A variation on the spirograph... a "Trirograph", also in Java.
