To call anything I've ever done more than a project would imply a level of perfection I have yet to attain.
Evolutune is a program to evolve little loops of bloops and beeps. I wrote this for a class, so I had to write it in C++ using Borland for Winblow$. It only runs on Winblow$, so far as I know. Maybe I'll try running it in Wine someday if I were to ever get MIDI figured out on this thing.
Here is a Grease Monkey userscript that uses the AIM API to put a status icon next to somebody's AIM screenname on their Facebook profile. From where it's hosted on userscripts.org it has been installed 6394 times as of 5/10/07. So, probably the most-installed thing I'll ever write...
Here is a BASH script I wrote for more easily accessing .lit format e-book files using clit. Basically clit will convert a .lit file into a directory with some html files inside of it. I was tired of calling up clit from the command line and littering my collection of e-books with directories full of random html files. This script puts the directory clit produces into a temporary directory, and then opens a table of contents of the directory in your browser (default is firefox). You need a working installation of clit to use this script.
Or, if you're running Mac OS X 10.something, install this. It is an application wrapper for the above script that I made using a nifty program called Platypus with the help of another nifty program called Cocoa Dialog. It comes with a pre-compiled clit binary, so it should be ready to go from the get go if you're on a PPC mac. Probably won't work on an Intel mac.
