The folks over at PlatformNation will be holding Playapalooza, a 50 hour gaming marathon on August 14th to raise money for Penny Arcade`s Child Play charity. The event will be streamed on Ustream.tv and you`ll be able watch gamers as they play games in 30 minute increments (gamers gotta eat and sleep you know). Sounds like a fun and it`s for a good cause.
