This neat multi-touch table demonstration of 2D Boy's puzzle game World of Goo was hacked together at Berlin's 26th Chaos Communication Congress (26C3) last December. According to Youtube poster Inh2l, this setup uses the Linux edition of the game (which supports multiple mice) with the Vinput software suite to make World of Goo work on supported multi-touch devices.

This video reminded me that 2D Boy revealed plans to develop an iPhone version of World of Goo last October and actually managed to get it "running well" on the iPhone 3GS -- I hope they're still working on the project. Considering that the upcoming iPad will be able to play iPhone games, I imagine that World of Goo for iPad would look/play a lot like this!
