Lets mourn the loss of all those old projects that just weren't backed up well enough. Here they are in reverse chronological order:
Kraterbikes - an internet multiplayer deathmatch in space - the revision control and wiki were hosted on the school's site dforge.ucsc.edu and they lost all data for all their hosted projects.
Bouncy Physics - a nifty demo of squishy stretchy circles within circles in ruby+opengl - my host had a raid failure that destroyed all data, my school account closed when I graduated, and my laptop hard drive suffered blunt trauma.
Flying Forkmonkeys - fight off a swarm of flying monkeys with your sword in this simple side-scroller I made in a summer at digipen - I forgot to back up the game when I left.
Starcraft Bomberman - 12 levels of 5-player co-operative bomberman as a scripted starcraft map - my hard drive melted.
Little Tank - a series of driving/shooting minigames made in director - that melted hard drive again.
