Interactive Petroglyphs
A sweet mashup of virtuality and physical presence is this artwork by Golan Levin. Called Ghost Pole Propagator, it projects a “skeleton” of each visitor onto the stone walls of a castle. This projected stick figure then mimics the actions of the visitor(s). You are the show.
Golan Levin is an ace programmer in Processing, a language that herds massive numbers of visual fragments, which he applies in art works.
