An interactive holographic installation featuring a white-light reflection hologram beneath a small pool of water, set into a frame of broken asphalt. When viewed from a distance, it appears to be a misplaced pot-hole, and the sounds of a street are heard. Moving closer, and peering into this pot-hole, a holographic image of a frog and a stream bed suddenly appears. At the same time, a motion sensor positioned near the hologram detects the viewer and triggers digital electronics to replace the urban sounds with those of a stream. Moving away from the installation, the image vanishes, and the street sounds return.
