Artist Statement:

    Where is the moon right now?

    Moon Pointer is a slow-time kinetic sculpture that continually points at the moon, wherever it is located, whether above or below the horizon, in daylight or night, clear skies or overcast. A computer-controlled mechanism will calculate the current position of the moon as viewed from the city of Gwangju – and point to it. The pointer will describe a continual presence to the moon’s movement. Its design refers to the history of scientific instrumentation, the timing is incremental. It is formally and mechanically minimal – and calculated to perform the singular task of tracking the moon. By tracing the entire path of the moon’s complex movement, the Moon Pointer offers viewers a heightened awareness of their spatial and temporal place in the universe and a series of insights into the most frequently considered object of vernacular celestial observation.

    The Moon Pointer consists of a computer-controlled mechanism that computes the location of the moon by accessing locally stored ephemeris data in accord with the current local time. The time is acquired by reference to a local real time clock module and checked against network time via a Wifi connection. The computers use these positions to run a set of motors that move their respective pointers to the correct azimuth and elevation. Photographic images (from NASA) accompany the Moon Pointer and depict the daily phases of the moon as seen at lunar transit from Gwangju for the period of the exhibition. A related version was commissioned by the Western Washington University and the Washington State Arts Commission.
