Humble Mojam Bundle.

[Vy'drach]

Gonna basically copy paste this from the Ponychan /g/ thread about it.

Mojang and friends have one weekend to make your game -- live!

The indie studios Mojang, Oxeye Game Studios, and Wolfire Games will be livestreaming all the glory and drama of making brand new games in 60 hours. Based on a poll of more than 100,000 users, Mojang and Wolfire will be tackling a real-time strategy shoot 'em up, with a steampunk, ancient Egypt theme! Oxeye Game Studios is crafting a dungeon crawler beat 'em up set in a post-apocalyptic World War II!

Pay-what-you-want for the game any time during the jam. Use the form below to support vital charities while getting get access to the games-in-progress.

All proceeds go to charity! You can support up to four vital non-profit organizations: The Child’s Play Charity, the Electronic Frontier Foundation, the American Red Cross, and — for the first time in a Humble Bundle — charity: water, a non-profit organization bringing clean, safe drinking water to people in developing nations.

It's worth checking out just to watch the guys working on the games.
