The Lunar Persistence Apparatus is a robotic sculpture consisting of a teleprojector and a computerized motor assembly that strives to project a duplicate of the Moon in the precise direction of the Moon forever.
Using GPS and a digital compass, the Lunar Persistence Apparatus ascertains its latitude, longitude, altitude, and heading, as well as the current universal time. It then references a table of lunar positions and phases and adjusts its phase mechanism and its dual motors as it attempts to align itself with moonbeams, casting its own light into the infinite abyss of space.
During the day, The apparatus continues to indicate the lunar position even when the moon is underfoot. Walls and even the ground become suddenly transparent— but only to Moonbeams.
