|CANAL DEMONSTRATION PROJECT
Etched into the table is an ancient Hohokam drawing
of the 2000 year old canal system. Periodically water
flows into the map, fills the grooves, evaporates,
and then fills up again.
Standing on the raised platform, the viewer�s
shadow marks the hour.
Water from the trough spills over the wall onto a grid
of stepping stones. The stones absorb and evaporate
the water to cool the room.
