We have covered many awesome kinetic sculptures here in the past. The Flux Optical Illusion kinetic sculpture by Ryan Kvande is quite special. It is attractive when still but creates amazing patterns when in motion. No battery is required. The sculpture works with a simple spin of the hand.
Flux has a modular design. It is handcrafted from Russian Baltic Birchwood and is 31 inches wide. It makes quite awesome trippy patterns. What more can you ask for?
