a 3D data sculpture of the Sunday Minneapolis / St. Paul public transit system, where the horizontal axes represent directional movement and the vertical represents time.

the piece titled "bus structure 2am-2pm" is constructed of 47 horizontal layers, each forming a map of the bus routes that run during a given interval of time. looking down from the top, one sees the Sunday bus map of the Twin Cities, while looking from the side, the times appears as strata building upwards. within each layer, every transit route that operates at that time is represented by wood balls placed at its scheduled stops, connected by the horizontal copper rods. each route moves through time and space differently, carving out its own trail that may or may not meet conveniently with other routes.

in total 42 routes, 47 intervals of time & 296 bus stops are depicted by about a half-mile of copper rod & 6,000 wood balls, suspended in the air by hundreds of blue threads.
