For those of you who are unaware, speedrunning site Speed Demos Archive is hosting their third annual Awesome Games Done Quick charity marathon- roughly a week of live streaming 24/7 video game speedruns. AGDQ1 9CGDQ) raised ~$25k. AGDQ2 raised over $50k. This year they're a bit over half way through and well on their way to $100k. All proceeds go to the Prevent Cancer Foundation.
It's really an awesome event to tune into, as they also have a live-in-room camera stream and do crazy special events like a (now past) Castlevania run with the background music performed live, a 2-players-1-controller Contra run (upcoming) and donation prizes for nearly every game.

Oh, and the grand prize drawing for donations of $30+ is a replica OoT Master Sword. Like, actual to-scale metal custom work.
