2009 Global Game Jam Keynote by World of Goo creator Kyle Gabler, in his distinctive whimsical style. The keynote is as inspiring in non-game-related ways as World of Goo is, by which I mean a surprisingly large amount.
Kyle's blog entry includes follow-up links to games shown in the keynote.
Global Game Jam 2009 ended on Sunday. The site includes a directory of 48-hour game projects produced during the jam.
