Optical illusions show how we see | Beau Lotto
TED

Neuroscientist Beau Lotto runs the audience through color and pattern illusions to show that perception is shaped by context and evolutionary history rather than being a direct readout of the world. The talk is playful and hands-on, and it argues that the brain interprets ambiguous signals.
HN commenters use it as a fun, accessible demonstration that color perception depends on surrounding patterns and that what we see differs from what the eyes register.
