If it moves, twinkles, reacts to light, sound and movement then there’s a place for it in the Kinetica Art Fair. Tucked away in a huge basement opposite Baker Street station The Kinetica Art Fair showed a fascinating array of cutting edge kinetic art ranging from the best in digital technology to smooth movement of levers to the simple spontaneous movement made by opposing magnets, dodging in a dish. I particularly liked the impressions of human form which appear to hang in droplets of light.
