Doug Aitken, "100 Years"

The L.A. artist known for elegantly striking video installations turns to site-specific sculpture for his latest show, which does quite a bit of interior demolition to get the job done. A circular hole blasted through a wall, for example, frames the word sunset, spelled out in backlit letters that appear to be carved out of volcanic rock. A crater excavated in the middle of the floor serves as the catch basin for the exhibition centerpiece: a "sonic fountain," in which five nozzles suspended from the ceiling release timed squirts of cloudy water to created a symphony of droplets. It's all a little nutty, but also mesmerizing.
