Just first google search it or maye even go to chat rooms about artwork.
Reply:The only way to correct his mistakes would be to build it as is and have a fixed point of view where the illusion would still work. The law of physics would still remain tho.
Reply:What do you mean "solutions of"? They are illusions, and are meant to fool the eye. They aren't meant to be real or buildable. They are meant to challenge perception and stretch imagination.
