Warning: do not watch this if you're epileptic. Don't watch it if you're on your way to a meeting or about to write an article, either.
This video will allow you to hallucinate without taking any drugs.
It utilities the motion aftereffect illusion (MAE) where your brain will make stationary scenes around you look like they are moving, provided you have been looking at dynamic visual stimulus for a fixed period.
A small caveat: while this clip advises views not to blink, we think it means "don't blink too much" rather than "don't blink at all". Also this works best in full screen. Happy Friday!
