Cliff Pickover, I believe is the first to demonstrate this illusion. on his site he states the following:
I am conducting a fascinating ESP experiment. Recent statistics suggest that my system can predict the correct outcome of your choice with 98% accuracy.This is not one of those cheesy number game tricks. It is so convincing that The Daily Mirror of the UK said the following:
"It's got to be one of the weirdest sites we've ever come across but it's definitely worth visiting. Pop into http://sprott.physics.wisc.edu/pickover/esp.html and you'll be baffled for days - even months. We don't know how he does it but Cliff Pickover, the site's creator, claims he's conducting an ESP test. Click on one of three eyes, he asks, and then look at six playing cards. Without moving your cursor, pick a card, shout out its name and then click on one of six more eyes. It then tells you which card you chose. It claims to be correct 98 per cent of the time but won't tell you how. Every one of the 60 times we tried - and we did everything we could to trick them - they got it right. Spooky!" (page 45)Cliff has a great site, but in this review they claim to have gone through the experiment "60 times" and "we did everything we could to trick them" only for Cliff's site to guess correctly all 60 times. Admittedly this parlor trick is fun but before those at the Mirror start accusing people of being dumb here in the United States (frontpage Nov 4th) they should take a look in their own mirror.
Go to Cliff's site and check out this illusion for yourself, it is definitely worth the visit. If you can't figure out how it is done check the explanations on the site. If you still can't figure it out check the comments below.
