Flux.tv is putting on the world's first film festival dedicated to iPod-size videos. There are already dozens of submissions in the categories of Student Film, Indie Film and Music Video.

Vote for your favorite through April 15. —Mike Haney
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
