Animated Vines is an interactive paper installation that comes to life in the presence of a viewer. Normally a static wall hanging, as the viewer approaches the vines begin to curl and slither up and down. Each vine is made up of eight units, and each unit actuated to curl using muscle wire sewn directly to the paper. While a single unit can only curl slightly, cascading the units sums the individual movements to create a lifelike dance. The muscle wires� movements are silent so that the interaction is accompanied only by the sound of gently crackling and creaking paper.
