Four sets of 4 letters rotate to form random words. The letters are installed in the 3 exhaust vents from the underground parkade and turn with the outflow of the exhaust fans.

This piece is based on, and dependent upon, a part of the mechanical systems within the structure of the building. The work consists of a series of four four-letter word groups mounted within the 20 X 92" exhaust airduct vent grills exiting from the underground parking ventilation system... The vents face out onto the pedestrian sidewalk that runs along Pacific Boulevard... The front faces of the letters are highly polished aluminum and are visible only for the moments that they are exactly perpendicular to one's direction of view. Rotating slowly in the existing flow of air, each block is independent of the next, causing a randomly changing array of letters, occasional words, and sometimes sentences to be swept into the pedestrian world. The word groupings are derived from four subject areas: active : work, rest, play; architectural: post, beam, wall; social space: city, park, yard; and weather: wind, rain, smog. ..."
