Lately I have been really interested in brain tricks, brain teasers, and optical illusions. I had the chance to work on the expanded brain teasers section of our website, which introduced me to a whole host of terrific illusions and tricks.
My work on that led me to this funny and surprising video featuring Al Seckel, cognitive scientist and perceptual illusion expert. He illuminates several truly fascinating brain tricks here, many created by him and his colleagues. From DaVinci’s hidden images to impossible shapes, and piles of junk that turn to pianos before your eyes–if you’re wowed by all the ways your brain and perception can trick you, I highly recommend this video.
