This is "Platform Diving" by Deborah Brown made with Glass Mosaic in 1994 in the Houston St station.
Deborah BrownÕs Platform Diving shows realistically rendered marine animals doing oddly human things. A manatee is patiently anticipating the arrival of the next train. A whale reads a commuterÕs newspaper over his shoulder. Turtles dive off a platform of the station. ÒI wanted to explore the analogy between subway travel and the movement of our fellow creatures through their natural environment,Ó Brown says. ÒUnderwater creatures navigate a complex spatial array of undersea passageways, much as we maneuver through our own manmade systems. I thought it would be provocative to portray them in a part of our world most closely resembling their own, but involved in activities familiar to us.Ó
