A high-resolution color transparency of the floor of Grand Central Terminal in New York, as seen from above, is mounted on brackets in front of a panel of 1728 white LEDs. Programmed with custom electronics, the LEDs flicker with low resolution, video-based imagery of people walking through the same space as the photograph. As with all of Campbell's LED works, the piece explores the limits of perception, in this case by juxtaposing still and moving imagery. The low-resolution walking human figures are only comprehensible as such because they are in motion. Paradoxically, as the viewer moves further away from the piece, the walking figures appear with more definition & clarity, while the photographic image becomes less distinct.
