The latest installment of Awesome Games Done Quick is due to start soon. If you love speedrunning done for charity, you're in luck.
The Games Done Quick events are held every year in the winter and summer by the Speed Demos Archive group, and are popular enough to attract the sort of attention needed for a nice big charity fundraising event. This next one will take place on Sunday at 5pm British time, which actually means it'll start later today for those of us in the UK. Visit the Games Done Quick site for your timezone if you're not in the UK though just so you don't miss it, and also to get a peek at the schedule.
It'll last a week and the 9th seems a good bet for PC gamers as Half-Life: Opposing Force, Episode 2, Portal/Portal 2 and Aperture Tag all make appearances that day.
You can view the event from the main site for GDQ or via their Twitch stream. The donations are going to the Prevent Cancer Foundation this time, so it's for a very good cause.
