DrPetter, the brilliant mind behind sfxr, was inspired by the awesome Unfinished Game Demo/Dump thread on TIGForums and decided to contribute a mosaic of 116 of his own unfinished creations.
You can see the full image here (3 mb) – wow, is that ever fun to look at! DrPetter has also written short descriptions for each of the games (some of which can be played at his website)!
Definitely check out the rest of the dumps, too. You might not think it, but it’s quite inspiring (and entertaining) to see people’s unfinished work. I’m considering contributing some games to it myself!
