Despite overwhelming evidence to the contrary, there still exist some people on planet Earth who believe it's the only celestial body humanity has ever walked upon. You've heard it before -- the moon landing was a hoax, a mere TV drama produced by Stanley Kubrick presented as fact to dupe the Soviet Union into giving up the space race. This deliciously ludicrous conspiracy theory has been debunked countless times, but now its advocates have one more refutation to deny: NVIDIA's Voxel Global Illumination tech demo. It's a GPU-powered recreation of the Apollo 11 landing site that uses dynamic lighting technology to address common claims of moon-deniers, and it's pretty neat.
