• ID Code: O4-36
  • Purpose: Perspective illusion.
  • Description:

    Opening the box and viewing the system from above, it appears to be only a random collection of sticks. When viewed through the peephole at the front end, the sticks appear to form a chair.

    This illusion and many more like it were made by twentieth century Dutch artists who didn't have enough to do, forming an entire branch of modern art: the "perspective cabinet."
