Throughout the ages bioluminescence has inspired myths. Long ago, sailors in the Indian Ocean encountered massive bioluminescent blooms as they sailed through the water, lighting the wakes of their ships like the spokes of a wheel carrying them to their destination in a chariot of wind and water. They called this phenomenon “The Wheels of Poseidon." Our goal is to harness the beauty of bioluminescence to create a new medium for artistic expression. We will generate a living, programmable bioluminescent display, with pixels and voxels built of bioluminescent plankton (Pyrosystis fuciformis) floating freely in the water column and stimulated to glow by a programmable pattern of pressure waves (acoustic waves) in the water.
