This Optical Illusion Video Uses The Steep Hills Of San Francisco To Confuse Your Brain.

San Francisco is known for having a lot of interesting people, fantastic architecture, and dozens of massive, steep hills. As such, it was the perfect place for Ross Ching and Karen X. Cheng to make this amazing video.

The concept behind the video was simple: Using a "titled camera" effect, Ching and Cheng could film themselves on the steepest streets of San Francisco and start playing with the illusion of being on an incline. The finished product is creative and extraordinarily cute, and we'll bet you won't be able to watch this video with your head tilting to the side.

These 29 optical illusions will make your head spin.
