MC Escher Relativity. I felt this was a very interesting optical illusion. I think it is amazing how someone had the creativity to come up with this. It looks like you constantly have to rotate the image to get the full effect.here are windows and doorways leading to park-like outdoor settings. All the figures are dressed in identical attire and have featureless bulb-shaped heads. Identical characters such as these can be found in many other Escher works. It can be appreciated through a perspective and representation of a 3D and 2D picture.
