Watch this video of:
“Morpho Towers--Two Standing Spirals” is an installation that consists
of two ferrofluid sculptures that moves synthetically to music. The two
spiral towers stand on a large plate that hold ferrofluid. When the
music starts, the magnetic field around the tower is strengthened.
Spikes of ferrofluid are born from the bottom plate and move up,
trembling and rotating around the edge of the iron spiral.
