See a Live Action Checker Shadow Illusion [Video]

Commonly depicted in graphic form, this video showcases the well known Checker Shadow Illusion as a live action sequence.

The Checker Shadow Illusion–published by Edward H. Adelson, a Professor of Vision Science at MIT–is a popular optical illusion. In the illusion a square in the shadow of a cylinder is show to be exactly the same shade as a square outside the shadow, despite the two appearing very different to the eye. In the above video we’re treated to a live-action demonstration where the color of the squares seems to shift, chameleon like, right before our eyes.

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    Nice; would of like to see her switch the cut out square to other square but not in the shadow of that canister?
