“RE: is a 360° projection mapping installation that uses mirrors to allow a projector to project onto its own surface. The mirrors bounce the projections back onto their source. Virtual pixels become points of augmentation in actual space. ‬In most cases the projector has a functional role within a video installation; the projector in RE: functions as a symbol for both sender and receiver of the medium of light.”
