Ed Devane has mounted an installation in the South Tipperary Arts Centre consisting of two new sound sculptures that interact with visitors through mechanical and electronic means as well as collaborative approaches. Visitors create sequences of musical sounds. A collection of acoustic and electronic sound sculptures hanging from the ceiling react to foot traffic below in unpredictable ways: a degree of uncertainty and randomness is baked into the logic underlying the system. Taking this idea of unexpected results a step further, and in a way designed to involve a deeper engagement from exhibition visitors, the second piece presents a physical sequencer in the form of a large rotating disc that activates sounding processes and events.

Chance and randomness come head to head with determinism and the will of the system.
