There's a french artist who is doing that kind of things for many years... I'll try go grab its name, his work is even more impressive.
yeah, the guy who draw on the street in a deformed way that makes the image stand out when seen from a certain angle? Would be really cool if you found those pictures, they're pretty sweet. The cool thing on this one is how they take multiple surfaces and different forms and length to create something so precise, they must have calculated and mesured everything to death, and you only see what those weird lines are when you look at this particular place.
