Ferrofluid Sculpture that Responds to Sound

Designer Russell Garehan's 'Ferrocious' is an electronic ferrofluid sculpture which has an electromagnet (the orange/gold wires at the top of Ferrocious' glass tube) which is powered in response to sound and causes the magnetic ferrofluid to move to rhythm of your voice, the beat of music, or any low-frequency loud noises. Its typical response range is around 250hz and lower, meaning it responds best to things like vocals, percussion, bass guitars, bassoons, violas, cellos, and quite a few other instruments in the lower frequency range. Put it anywhere and find yourself constantly trying out new music on it to see how it reacts. Seeks funding at Kickstarter.
