This is Doug Aitken's Mirage, one of the showstoppers of Desert X, an exhibition of 16 site-specific monumental works by international artists that spans southern California's Coachella Valley.

The works are mostly "land art", massive installations in nature. The exhibition includes a replica of assassinated president John F. Kennedy's nuclear shelter, a mirrored fence, a wall of optical effects, a traditional earthen shelter and an anti-social robot.
