The Fast Forward Film Festival (formerly the 5x8 Festival) now has a website. The FFFF gives 30 teams 21 hours to make a 3 minute movie. Wusses. They get to use editing and everything. We make a 45 minute movie in an hour. Woo-oo!
(In "but seriously folks" mode, I've seen some beautiful work at the FFFF. Some 3 minute pieces of mess, too, but some wonderful, wonderful stuff.)
