Well its about 10 years too late for some of this stuff but I figured I'd open the source to my dead projects I have lying around. Some are pretty raw, like my flocking applet from a college course, while others are completely functional and dare I say beautiful code, like my X10 Java library.
FlockingApplet - a graphical applet that simulates the flocking behavior of birds. handlecheck - a web app that searches the web to see if your favorite username is taken. gwt-common-widgets - a collection of Google Web Toolkit widgets x10-java - a Java library for home automation.
