Sometimes things aren't what they appear to be, and here's a case in point: the floor of this elevator car is painted to give the illusion that there's no floor at all. It's a trompe l'oeil that's realistic enough to convince the roadrunner that there is indeed a tunnel on the side of the mountain, not just a painting by Wile E. Coyote.
The artists sell the illusion really well, too, where there's even a sign warning you there's "work in progress." After a few people walk in, though, you'll be able to see the footprints, and the illusion might not be so convincing. But I'd still like to be the first one to step inside.
