TL,DR: people claim the moon landing was a hoax because the lighting in the images don't accurately reflect the way Aldrin would be lit up. So NVIDIA uses global illumination to recreate the lighting conditions and find out how accurate the images are...
Worth watching. 40 Minute interview with Gordy, who is my hero from when I was about 8. In 2001 he came 3rd in the world. Now I ride bikes with him.
Goes from how he rode as a kid, to how he nearly died in an accident (didnt mention how he had to have an emergency trackside transfusioN). Absolute hero to me.
