“R” is a giant wooden kinetic sculpture made of thousands of hand-carved components. It constructs an image with thousands of black and white ping pong balls in respect for humankind’s endless efforts from Altamira cave’s drawings to splendid images on light emitting diode matrix displays.
The piece works in two modes. In passive mode it constructs ready-made images by stacking up black and white ping pong balls in predefined orders. In interactive mode, the piece detects human activity nearby itself and drops ping pong accordingly. As time goes by, like bones of dinosaurs in stratum, spread dots of black ping pong balls accumulates leaving traces of visitors that passed by.
