You know that part in Inception when gravity gets all crazylike and nobody knows what's real and what's an illusion? (Okay, that's pretty much the whole movie, but still.) Artist Julian Hoeber's “Demon Hill” exhibit at the Hammer Museum gives you the chance to experience that very feeling for yourself, in a waking state. On Hoeber's cross-country drive to Los Angeles, he stopped off at various gravitational “mystery spots” along the way, marveling at these strange places that alter physical reality. He took inspiration from these cosmic marvels to create an artwork that's “part minimalist sculpture, part roadside attraction,” as curator Ali Subotnick describes it. Visitors enter the bizarre, tilted, house-like structure to find their perceptions may not reflect reality — as in, everyone inside is standing at a seemingly impossible angle, balls seem to roll uphill, that kind of thing. Your inner ear starts messing with your mind, and though you'll have no idea what's going on, you'll likely suddenly demand answers, as Hoeber did during his mystery tour. Lucky for you, the artist isn't stingy with his secrets, unlike many of those who run the mystery spots. Here, guests are allowed to walk around the structure and discover how it works.
