Upside down (Schröder) Staircase illusion in 3D

submitted by noims

2 years 11 months 3 weeks ago

There's a relatively well-known illusion where a picture looks like a staircase, and when rotated the illusion breaks until it pops back at 180 degree rotation with the stairs in reverse order.

This is demonstrated in this video, but they've also made a 3d version that I find even more mind-breaking.
