515 13th St. San Diego, CA “Shade Tree” at Parkside is an abstracted tree. The light interplay with this sculpture is as important as photosynthesis is to a living tree. Shadows by day, lighted at night. There is also a walking map to find other trees of distinction close by. The shadow play continues with an additional sculpture in the lobby.
