Rafael Lozano-Hemmer, ‘Pulse Spiral’, 2008-2012, bitforms gallery

Dimensions variable, from 400 to 900 cm tall and from 300 to 700 cm in diameter.

The layout of lightbulbs for "Pulse Spiral" is based on the Phyllotaxis Spirals that are naturally derived from Fermatʼs equation r=±ø^1/2. This pattern creates a spiral with the golden angle of 137.5o, which is often found in nature, for instance in sunowers. It turns out this pattern produces the most even--and beautiful-- three dimensional distribution of lightbulbs, forming a spiral paraboloid.

"Pulse Spiral" records and responds to the heart rate of participants who hold a sensor underneath. Originally commissioned for the opening of the Center for Contemporary Culture in Moscow in the constructivist Bakhmetevsky Bus Garage, the piece was inspired by engineer Vladimir Shukov who worked with Melnikov on this emblematic building from 1926-28.

About Rafael Lozano-Hemmer

Electronic artist Rafael Lozano-Hemmer's public art installations combine technology, architecture, and performance using devices like robotics, projections, and cell phones. He constructs "temporary anti-monuments for alien agency," as in Pulse Tank (2008), in which heart rate sensors send ripples across the surface of water, or the Guggenheim's 2009 installation Levels of Nothingness, which allowed people to speak into a computer that linked voice traits to colors that were projected across the room. His Vectorial Elevation (1999), in which 800,000 participants created searchlight sculptures above Mexico City, may well be the world's largest interactive artwork ever.
