This is a random collection of links to things that I did, worked on, or in some way had a creative hand in.

• Audacity, a cross-platform digital audio editor and analysis tool. I'm the project leader and primary programmer.

• wxWidgets, a cross-platform GUI toolkit. Audacity heavily uses wxWidgets, and I'm involved in the wxWidgets development community.

• XaoS Fractal Zoomer - I ported this program to the Macintosh.

• libresample - I needed a free, non-GPL resampling library for Audacity, so I ended up writing a new library based on Julius Smith's resample program.

• PortAudio - another library I use heavily in Audacity; I've done a lot of work on the Mac OS X and OSS ports of this library, and I also contributed PortMixer.

• Search Engine for Mathematics Magazine and College Math Journal - I wrote the user interface and search engine while I was at Harvey Mudd College.

• Desdemona, Interactive Othello for the Web - I wrote this online Othello player with Whit Myers back in 1996. It's showing its age but still has the distinction of one of the few board games you can play on the web without Java, JavaScript, Flash or any plug-ins.

• My solution to the Firing Squad problem (a fun theoretical computer science puzzle). This web page contains an interactive, colorful and animated illustration of the solution I came up with when I took the Theory of Computation (TheoComp) class at Harvey Mudd College in Fall of 1996.

• Uncrossed Knight Paths is NP-complete - a writeup of a proof that even determining the winner of the game of Twixt is a computationally difficult problem. Kevin Watkins deserves the credit for coming up with this proof; I improved on it and wrote it up.

• Aaron's Budapest Restaurant Guide - I contributed a couple of the entries after my semester in Budapest.
