Apologies to Terry Pratchett for the title. I could not resist. If you have not read the book, you should.
The Chaoscope monthly contest has ended and despite some votes from my loyal friends, my entry did not make the grade. The winning entry looked remarkably similar to the image below which is the same attractor as "Infinite Pretzel" but rendered in a different mode.
It is amazing what a small change can do to an image.
