"SERIOUS" - This work was done also in a tunnel. It spells out "SERIOUS"... Your basic flat piece,...no 3-d, you may notice the dark rectangles on the right and left regions of the piece. These were called "color squares"...they gave us the excuses needed to break up the spaces in a piece. The idea was that they were windows to another plane, so we could fill them in with a wholly different and abstracted color pattern. And still maintain a sense of balance within the whole piece...
