54 x 5 cm diameter, 10 cm diameter at base.

33 x 20 x 4.5 cm satin chromed steel and hemispherical glass lens.

Denslens was one of four sculptures I made in 1974 using a wire-wrapped rotating cylinder and an emblematic lens.

The object is also an event, since seen from any other angle, the lens cylinder pair is simply two separate objects. It is only when the viewer is aligned with the pair that the visual event can take place.
