Ames Window Optical Illusion

An Ames Window is an object that looks like a rectangular window, but in reality, is a trapezoid. As the window rotates on a vertical axis, it first looks to be going in a certain direction, but after turning 180 degrees, it gives the illusion of stopping and reversing its course. Observe as the rod inserted in the middle seems to be passing through the frame as the device appears to be reversing its rotation.
