Like the MythBusters? Then you'll probably like this small Flash-based movie viewer created by the folks at the Discovery Channel. It lets viewers pick from four clips of high speed footage from the show, including one massive explosion, two clips of sliding into baseball bases, and crash test dummy Buster bursting into flames--all in frame-by-frame goodness.
Users can toggle the viewer to work either with their mouse, or use their keyboard to go frame by frame. The mouse gives slightly better results, letting viewers go back and forth quickly for great effect. Which one is your favorite?
