The Ambiguous Cube Illusion

At first it may look like a normal cube. But this cube is whimsical, and may suddenly turn into something else. You can empower the transformations by concentrating a little.

The first aspect in this figure is as a cube as we usually see the figure. Now look at the cube, and in your mind's eye, turn it inside out. Try to make the figure appear as a room with two walls and a darker floor. Once this aspect is realized, the figure takes on a brand-new 3D appearance. Remember—all this is happening inside your head!
