The House That Swift Built Optical Illusion is one of those three dimensional 2D pictures sent in by Jen S. This picture is real neat in the fact that your mind is all over the place trying to figure out how it all works. Are those stairs going up or down? These types of illusions are generaly inspired off some of the works of MC Eschers Works. Such as Escher’s Belvedere, Escher’s Ascending Descending stairs or the famous Waterfall Optical Illusion. So with all these mind games can you get a good grasp on the reality that exists in this picture!
