Impossible Cube Optical Illusion is one of those impossible object optical illusions that can really mess with your mind.  If you look at all the edges of this cube they seem to cross over each other in a way that just doesn’t hmake sense.  A similar but simpler one is the Impossible triangle Optical illusion (only easy cause it shows you how its done :P) So any ideas how this imposable square is done?
