OK; made a tutorial for this one (Wallace broke my arm). Similar workflow for Opus Musivum, which is actually easier to do. Not doing the Voronoi tutorial since it's way too much work for a lazy guy like me (so was this one; you folk are luck. lol). The result has no grout or texture (transparency embedded).
