Headless skeptic

My evil twin, psychologist and skeptic Richard Wiseman, has another winner: a video playing with your blind spot.


Very cool! I love illusions, and so I used to do all the blind spot tests when I was a kid... but I never knew this about it. I have lots of ideas about how this might work, but I'll have to do a spot (haha) of research on it.
