Paris based artist Felice Varini paints geometric designs onto buildings. The trick is, you must be standing at an exact point to see them, otherwise they appear as random broken lines (as seen above).
Artist Felice Varini is a master of anamorphic installations. He paints directly on indoor and outdoor spaces such as rooms, stairways, buildings, and more. His work requires that you view it at a specific angle, so that you can see geometric shapes.
