Echidna at SIGGRAPH Art Gallery

Tine Bech of the University of West England and University for the Creative Arts presents Echidna, an interactive sound sculpture that is a fussy, tumbled creature that has its own (electronic) voice. When the creature is touched, and the electromagnetic field around it is disturbed, sound emerges. Undisturbed, it hums happily, but when it is touched it squeaks and reacts to human presence. The work combines a circuit that directly measures electrostatic changes in the environment and a custom-designed, phase-locked loop system that drives an audio speaker.
