6: Falling Tower Illusion

Go to the west side of the Campanile (Sather Tower) and look up. Stay still for a few seconds observing how the exquisite texture on the tower wall appears to converge toward the top. (That is not the illusion yet.)

Before long you will notice that the tower appears to fall toward you, with a constant angular velocity. To prevent the tower from crushing you, close your eyes.

This infamous illusion has bewildered the brightest minds on the Berkeley campus for decades. That’s probably why they put the “NL” parking places near this location. Can you guess what the “NL” stands for? Think Stockholm.
