nVidia gets owned again...Dawn Demo runs on Radeon!

Gooooooood morning ATI DX9 videocard owners! Know of that alluring NVIDIA tech demo featuring that half-naked fairy Dawn that GeForce FX owners like to run over and over again? Thanks to the super brains at the Massachusetts Institute of Technology, high-end Radeon owners will too be able to drool at this pixie shader creation.
Basically, a group of MIT engineering students have created an OpenGL wrapper that allows ATI cards to run NVIDIA's most famous tech demo with some pretty impressive results!
It runs 15% faster than NV30 on the 9800pro, and it also runs faster than NV35 (we are unable to personally confirm this but a user with both cards and FRAPS could).
Creates higher quality images than the original due to the normalization being done in a fragment program (dp3/rsq/mul) instead of in a normalization cubemap which the FX extensions does directly in hardware
The OpenGL wrapper adds more overhead, as it has to interperet code calls for Nvidia extensions and map them to ATI/ARB extensions, and yet it still runs faster on the ATI card, due to its more sophisticated pixel shader engine.
