I just saw the new Omnimax film that's playing at OMSI here in Portland.  What an amazing film.  I've seen a bunch of Omnimax films, and I think this was one of the more compelling.  It's composed of profiles of four people who go fast for a living: a sprinter, a mountain bike racer, a race car driver, and a race car designer.  All set to Mozart, and hosted by Tim Allen.  Very cool.  Lots of Omnimax-optimized footage of going fast.  Some of the coolest stuff was footage of the mountain bike racer, Marla Streb, who's been clocked at 67 mph, down a mountain on a bike.  That's pretty amazing. 

If it's playing anywhere near you, it's worth checking out.
