Where Is the Moon

Institute of Contemporary Art, Philadelphia, PA 18’ x 18’x 18’ Painted steel, laser, equatorial mount, lunar speed adjuster, motor drive, thirty 18” x 18” x 2” sandblasted Pennsylvania bluestone pavers.

A laser beam points to the exact position of the moon at each moment, following its lunar rajectory 24 hours a day. The laser’s red dot moves from the ceiling to the walls and across the floor as moon moves around the earth each day. A ring of stones on the floor is sandblasted with the phases of the moon, showing the shape of the moon for each day of the show, creating an animation of the moon’s changes. Dates are chalked on the floor adjacent to each stone.
