Ray (EIEIO) gave me the idea for this one, so I gave it a go (Thanks Ray). I grabbed a couple of chunks of pine 2X4, resawed in half, cut the blocks, sanded and painted with acrylic paint. The backboard is a leftover piece of oak (I think), and another partial piece of a backing style board. The dimensions are roughly 12" X 12" for the whole assembly, with each block being 2.5" X 2.5". For the layout, I measured and drew lines similar to a Tic-Tac-Toe board and tried to center the blocks thereon.
Let me know what your thoughts are - ways to improve (other than pitching it into the woodburner).
Thanks for taking and look and have a decent day.
