The Best Optical Illusion of 2019 Will Confuse and Wow You

Optical illusions are often fascinating. It’s amazing how little our brains need to become completely confused and mistake reality for what they think is happening.

Each year, a nonprofit Neutral Correlate Society picks one best illusion from the applications that come to their contest. This year, the winner is Frank Force and his illusion is Dual Axis, a loop animation that changes the moving direction from clockwise to counterclockwise, to up or down, all depending on how you’re looking at it.

You can check out his amazing illusion below.

Force is a game developer who lives in Austin. “I’ve worked on DOOM, Red Faction: Guerrilla, Psi-Ops, and Starhawk,” he shared with Motherboard. “A little over a year ago I decided to quit my job to focus more on the creative side of things and learn some new skills.”

Programming his illusion took a day while figuring out how to present it in the best way was the tricky part. He posted the code to GitHub for everyone who may be interested.
