Los Angeles-based artist Julian Hoeber presents Demon Hill, a freestanding structure based on the architecture of “gravitational mystery spots.”

The architecture of these shacks creates the illusion that gravity works at an angle, that water runs uphill, and that bodies stand at a sharp angle to the floor. “Mystery spots” claim to be an effect and marker of a geological anomaly or a supernatural phenomenon and the illusion is so convincing that it gives even rational people pause.
