No matter how long you watch Ian Cheng‘s video installations, the logic of what‘s happening remains out of reach. The artist himself doesn‘t know how his simulations are going to turn out.

These works seem to circle around themselves, which raises several questions. Gianni Jetzer met up with the New York-based artist for an interview.
