… guarding rocks. Here’s a photo of one of the security guards hired by the Los Angeles County Museum of Art to stand outside and guard a big rock (Michael Heizer’s Levitated Mass). She has a graduate degree in philosophy and says that her main task is to discourage people from climbing on the rock.
Separately, photographers will appreciate the Stanley Kubrick exhibit, which includes a gorgeous array of lenses (see these photos from the Sony NEX-6 camera that I am testing). The exhibit will remind you that before computer 3D modeling people were forced to be creative.
