Hi Kent,
That was one of the "major" questions at the camp!..."Who made the fish?"
That project was done by Bill White. It was a real show-stopper and everyone appreciated Bill's talent and excellent workmanship.
He sandblasted the fish on the back of a thick piece of glass (he mentioned the sandblast masking was laser cut), then chipped the edges using pliers and "frosted" the chipped edge perimeter to blunt the sharpies and give the nice effect. The coloring on the fish was carefully applied via an airbrush using translucent "candy apple"-type paints. The wooden base and groove that the glass panel sits in was the part done on his CNC machine.
