This is an impossible 3D Square Optical Illusion.



This is another version of the Impossible Square Optical Illusion.

This optical illusion is taking advantage of the 3D techniques of perspective angles and shading to create this impossible square. The surfaces and corners of the square in this drawing are not in the same position they would be if it were a normal square, drawn in proper perspective. The added shading helps the eye track the surface as intended and adds to the optical illusion.
