A fun little way to waste a few minutes at work. This video, which works best in full screen HD, creates an optical illusion that will give you hallucinogenic-like effects afterwards.

One chapter of the book — that’s out in paperback July 2 — deals with altered states and Sacks’ personal experimentation with hallucinogenic and mind-altering drugs in the ’60s. He says the first time he tried marijuana, it induced fascinating perceptual distortion. He was looking at his hand, and it appeared to be retreating from him, yet getting larger and larger.
“I was fascinated that one could have such perceptual changes, and also that they went with a certain feeling of significance, an almost numinous feeling.
