Raina is a kinetic sculpture consisting of a radially-rotating rainstick.
Raina is a kinetic rainstick constructed from a six-foot-long segment of modified polyvinyl chloride pipe. The pipe has been bisected and filled with more than 50 helically arranged wooden rods that are struck by pebbles, lentil beans, and BB-gun pellets. The pipe is attached via a chain drive to a large alternating current motor operating at a fraction of its rated voltage. The underpowered motor turns slowly, gently spinning the pipe on a ball-bearing axle. Immediately preceding concerts, Raina is activated, providing a subtle noisescape underlying each composition.
