This is really cool. The folks at Nvidia are running a contest to see who can come up with the best Pixel Bender filter. NVIDIA wants to see what you can do to make use of their GPU, so they figured a great thing to do would be to give Pixel Bender a spin.

They seem to be focusing on Pixel Bender in Photoshop CS4, but what’s great about it is you’ll be able to use that same filter in After Effects CS4 or the Flash Player. If you’re looking to get started, Lee has a couple of great Pixel Bender tutorials.
