Last year South African sprinter Oscar Pistorius blew people's minds when he came in second in a 400-meter footrace in Rome...without feet. Pistorius is missing the lower part of both his legs, and ran on two carbon-fiber "Cheetah" leg prostheses. A lawsuit followed (of course), and Pistorius was banned from international racing. But Pistorius appealed, enlisting the help of human augmentation guru Hugh Herr of MIT to dissect the argument that his Cheetah's gave him an unfair advantage in the race. Last week the Court of Arbitration for Sport upheld the appeal giving Pistorius the right to compete in this summer's Olympics in Beijing.

Yeah... an advantage, right...
