The 3D Lichtenstein House Optical Illusion plays with your eyes through an altered perception. What appears to be a normal house in the still pictures bit is actually made of three concave angles that appear to be coming out wards; this effect makes the house appear to always be popping out at you no matter what angle you view it. The third image below helps explain this a little more. The Video should give you a full understanding, this very cool yet impossiable illusion!
