Icarus
The elements rotate clockwise and anti-clockwise in a chaotic, seemingly random fashion - sometimes calmly, sometimes spinning wildly but interspersed with passages of calm. Mesmerising.
Wall hung (and switched by a remote sensing device so it only turns when there is a person present), Icarus exploits the power of modern rare-earth (neodymium) magnets to attract and repel. Powered by 230v synchronous motor working through a gearbox.

Nothing comes from Nowhere
NCFN began life as the prototype for Icarus & Seeker and has been tweaked many times since then.
