Exploring Optical Illusions: Tricks of Perception and Perspective

The video explores various optical illusions, starting with the Ebbinghaus illusion, where identical circles appear different due to their surrounding context. It then explains the Checker Shadow illusion, demonstrating how shadows can mislead our perception of color.

Finally, it touches on the historical use of optical illusions as magic tricks in China.
