A top-down computer circuit board in charcoal and white, with square microchips, solder dots, traces and round mounting holes. Three square microchip packages ringed with pins and tiny pads disguise the finder squares. Thick dark circuit pathways with rounded bends carry the modules, while thin blue-gray traces fill the white gaps. The strong dark-on-white contrast keeps the pattern clear, and a black border with bolt holes frames the board edge.
