Word of the reopening reaches Old Silas, your uncle's foreman, who kept these machines running for decades before the doors closed. He dusts off his cap and comes back. Kalabux is a steampunk puzzle about color. Lay brass pipework to carry the three primary paints from their vats, split and merge the lines, and mix exactly the color each jar needs before the truck leaves.
