Impossible 3D Stairs with Illusory Music

Haqqında

Follow these twelve steps as they go around in either direction. They seem go on forever and never get anywhere, no matter which way you go; up or down. Mouse over any step to hear a musical chord. Follow the music around in either direction. Just like the stairs, the music seems to go on forever in either direction; it's impossible to tell where it starts and where it ends. The stairs are called the Impossible Staircase, and the music is a piece called the Shepard Scale. Both are endless and impossible. Yet here they are.
