Commence game jam! Commence Mojam! Minecraft studio Mojang, a group of indie studios, and the folks behind the Humble Bundle have teamed up for Mojam 2, a 78-hour game jam that starts right now. Watch along via TwitchTV and be prepared to pay what you want for any new pixelated creations that catch your eye.

Set to run through Saturday afternoon, Mojam 2 features Notch and the team at Mojang as well as indie studios Grapefrukt, Ludosity, Oxeye, Game Studio, Vlambeer, and Wolfire Games. As the teams craft their new games, you'll be able to pick them up via the Humble Bundle website. Just make sure to kick a few bucks to charity while you're there.

We've seen Notch crank out some interesting projects via the Indie Speed Run and the like. Looking forward to seeing what he and the rest of the teams come up with this week.
