This is a TED talk by Beau Lotto. Beau Lotto is founder of Lottolab, a hybrid art studio and science lab. With glowing, interactive sculpture and old-fashioned peer-reviewed research, he’s illuminating the mysteries of the brain's visual system. "Let there be perception," was evolution's proclamation, and so it was that all creatures, from honeybees to humans, came to see the world not as it is, but as was most useful. This uncomfortable place where what an organism's brain sees diverges from what is actually out there is what Beau Lotto and his team at Lottolab are exploring through their dazzling art-sci experiments and public illusions. Beau Lotto's color games puzzle your vision, but they also spotlight what you can't normally see: how your brain works. This fun, first-hand look at your own versatile sense of sight reveals how evolution tints your perception of what's really out there.
