This strange YouTube video is mind-bending. The Ames’ Window is an amazing optical illusion. The object itself is a perspective trick. Your eyes can’t see the truth.

Adelbert Ames created this neat trick. Ames dedicated his life to understanding the eye. His research into optics was invaluable. But he is best known for optical illusions.

This window is constantly turning in one direction. But that’s not what you see. It seems to stop and switch directions. This is a really impressive trick.
