___Prickbot is a tiny, solar energy powered robot designed to run on the light of an overhead projector. This work was prepared for the Arts of the Overhead Festival. The robot, sitting on the projector platform, intermittently makes random rotating movements and pricks tiny holes in a thin aluminium sheet, transforming the projected image slowly from a starry sky into a supernova. The design is based on Mark Tilden’s BEAM technology.
