Well, I thought that I had produced an example of an MSS breeder but now I'm not so sure. The pattern works: it does exactly what I intended it to do, but I have reservations which I'll describe below. But, first the pattern. It is a Gemini puffer, travelling at (1024,5120)/36,460,658 which creates ...
