Came across this video today of this staircase (start video at around 1:40) at Rochester Institute of Technology (RIT) and have no idea how it works. I’ve been thinking of all possible explanations and nothing seems feasible. It doesn’t seem like the students know how it works either. Crazy.
Escher is the best kind of mindfuck.
