I've made a number of windows of apps in the past, some useful, some not. Most of them were just small apps to provide a small functionality I wanted to have at the time. Here I'll post some that might be still be usefull to people.
Winstick was probably the most useful thing I did. It is still
being used by people and I still get emails about it. It lets
you control windows with a joystick/gamepad (ie the windows
version of leanstick). Unfortunately I haven't worked on it
for a long time, and don't plan to.
Here's the last version, from August 2005.

I implemented a Convex Hull animation Java Applet for a Computational
Geometry course. The applet animates the Randomized Incremental Convex
Hull and Gift Wrap algorithms on the given input.
