Necker Cube

There are two ways to see a line drawing of a cube. Sometimes one face of the cube looks like it is at the front, and then the same face appears to be at the back. This is called a reversal. Notice how the cube reverses each time a block goes through it. This is because the block has depth cues which force a particular depth view to emerge.
