Rafael Lozano-Hemmer - Pulse Spiral, Responsive Biofeedback Sculpture 2008

Pulse Spiral is a three-dimensional spiral paraboloid made up of 400 lightbulbs arranged according to Fermat's equations, --an efficient spatial distribution along a surface which is found in plant phyllotaxis (arrangement of leaves and cells in roots for example). The piece records and responds to the heart rate of participants who hold a sensor underneath. Commissioned for the opening of the Center for Contemporary Culture in Moscow in the constructivist Bakhmetevsky Bus Garage, the piece is inspired by engineer Vladimir Shukov who worked with Melnikov on this emblematic building from 1926-28.

Technique
Heart rate sensor, computer, DMX controller, custom software, dimmer rack, 400 incandescent lightbulbs, generator.
