Szakaly got his start messing around with vector animations and now uses Tumblr as a platform to play with his experimental GIFs.

The afterimage
One type of optical illusion is called the “afterimage,” and you’ve seen them before: You stare at a thing for a minute or two, then look away, and you see something burned into your eyes. This one is particularly crazy. Stare at it for a minute, then look away.

Follow the instructions. And then after doing it, don’t follow them. The picture is in black and white.
