The first global game jam has been kicked off! Although I can't participate all weekend, I did help get things started at the local triangle game jam. You can check in on them with this ustream:
Icarus studios is being an excellent host, setting us up in their motion capture room and having wired up a LAN for us. We've got just under 20 participants, with 4 games in development (brainstorm names: Breeder, Tethered, Robot Swarm, Buttons and Mindy).
