Creative Commons is running what they’ve dubbed a “Public Domain Jam”: You have until the 24th to develop a CC0 (Public Domain) game and you could win $1,000.

The 1,000 bucks are coming out of Nick Liow’s pocket. He’s the guy who created the CC0 (and crowdfunded), paranoia-laden game Nothing to Hide, available as an online HTML5 web game, and also as a free download for Linux, Mac and Windows.

He also put together and crowdfunded the Open Game Art Bundle, an online resource from which game creators can download images, sprites, music, sounds and more.
