O4-31: TRAPEZOIDAL WINDOW
Additional Info
- ID Code: O4-31
- Purpose: Classic depth illusion.
-
Description:
The trapezoidal window is rotated at about one revolution per two seconds by an electric motor in the box. When the taller side rotates away from us, it appears to reverse direction and rotate toward us.
Everyone knows that any object appears to get smaller as it moves away and bigger as it moves toward you. Mind over matter!
