I wrote software for Google, but before that, I've built some things that others have found fun like:

• A Python Script that converts DOOM WADs into SVG
• And a Duke Nukem 3D version of the same thing
• The beginnings of Sierra Style adventure game engine in JavaScript
• A Sound Test for as many games as I can find
• An archive of AOL and Newsgroup posts from Counting Crows from the mid to late 90's
