Anaconda Bus Optical Illusion
You have no doubt seen cars and buses with advertising painted on them before. But this advertisement for a local zoo on the side of a public transit bus goes above and beyond. It is really well done and almost looks like something out of a bad horror movie. Despite the fact that the anaconda is one of the largest snakes in the world, it would be hard to believe that one could grow to the size required to crush this bus.
