A video installation
In PTOLEMY, Steina Vasulka circles inside a space, delineating its boundaries with a mechanized choreography of camera movement. This is a world of circular movement, a vertiginous dance of machines and ordinary objects. The installation of PTOLEMY, a four channel piece in a multimonitor matrix, further compounds the action; a disjunctive world circles to sudden, but inevitable, conjunctions. Light and shadow, reflections in mirror balls, and the camera lens itself trace an optical trajectory to a soundtrack of machine music. This installation will premiere at Ars Electronica 1990.
