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.

This illusion is a troll.
Nice; would of like to see her switch the cut out square to other square but not in the shadow of that canister?
