This project is done on a sheet of heavy 3/4? plywood, 48? (four feet) square, with a grid of a half dozen different kinds of nails and screws spaced roughly 5/16? apart (and some wire to do the lines in my signature). That means that there are well over 20,000 pixels in the project, and I’d estimate that there are in the neighborhood of ten thousand nails and screws! The metal and wood frame that the painting floats in uses 2x8s, so this entire thing weighs close to two hundred pounds.
