A Matchmaker Julia set with a single fixed-point attractor. One critical point is inside a cardioid near its cusp and this causes the coils; the other is outside a region similar to where the quadratic M-set has a Fibonacci sequence of bud periods.

(Clearing a backlog of images that had been rendered, but not yet published, when that mobo went boom. Hence the older hardware specs on today's images. You'll be seeing a mixture of the two for a while. Thank heavens it wasn't the harddrive -- it did manifest with the world's scariest error message, "DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER", but it was the on-board controller, DMA subsystem, or some such thing and not the drive itself or its cable. Drive would have been worst. Cable would have been best, $19.95 instead of over $500 to repair.)
