My buddy Tim is hosting a fundraiser in form of a gaming marathon. Basically, him and a couple of others will play games on stream for 24hrs+ straight to raise money for a charity. They've raised 64k$ so far with similar events. The next marathon will be in three days, starting July 15th. The charity organization this time around is "Free The Children". Check it out if you like games and giving back

EDIT. A bit over 10k$ was raised in about 80 hours.
