I have a couple of pieces of spalted honey locust around here somewhere. It isn't particlularly pretty, sections of it just seem to be browner than others with none of the defined lines like sycamore or maple. A couple of boards did turn into a cool freckle pattern, which is the reason I bought the lot. The freckle boards are also the only ones without punky spots, so it must be right on the edge of the spalted area or it wasn't left very long. I will see if I can find them and get a pic.
