Olduvai Cliff - Sam Griffin, Guy Wood, Jo Wills

The Olduvai Cliff is an installation based around the resonant frequencies of a room and 111Hz, a frequency that stimulates the portion of the brain that governs mood, and  the release of beta endorphins - the neurotransmitter responsible for feelings of wellbeing and relaxation.  111Hz is easily within the human vocal range and is a resonance found in buildings around the world from neolithic burial mounds to pyramids and cathedrals
