A digital rose engine may not make a good equivalent to an analogue engine,
but would provide some unique and beautiful patterns in its own right, by
nature of its quantization of movement. In my work with high-resolution
platesetters I have seen some stunning effects that use these interference
(Moire') patterns to good effect. Use what you have.

I'd love to see some pictures of that rose engine, BTW. Any chance of that?
