Works in the Frequency series are three-dimensional maps illustrating the accumulation of hours spent in certain locations of home cities since the start of the Latitude and Longitude Project. Each rectangular volume represents about 10 seconds of latitude/longitude or about 750 feet on a side. More time spent in a location increases the height of the column. Locations representing home, work, and the studio are very tall reflecting the relatively large number of hours spent at those locations.
