I've been programming since I was in junior high (back in the days of WWiV mods!). GroupVoice - (BSD License) - A team voice chat library meant for multiplayer games. It is available under a BSD license. Tiles.ice.org - (GPL) - A PHP-based collaborative art project (see it in action here). www.ice.org, the art group that I've been a member of for so many years. Like Tiles.ice.org, the code for www.ice.org is available under the GPL.
