In the early nineties, I spent a considerable amount of time writing a screensaver called "HOP - Fractals in Motion" that specialized in two largely unknown kinds of strange attractors, one of them called "Hopalong" - referring to the way the attractor pixels jumped around the screen -, the other one called "Gumowski-Mira" after the two CERN physicists who discovered it when trying to compute the trajectories of subatomic particles.
The software, "HOP - Fractals in Motion", was popular at the time but it is outdated - it was written in the Pascal language for the extinct MS-DOS operating system. It can be run on today's operating systems only using a DOS Emulator software. Few people use HOP today although it has many unique features that I haven't seen anywhere else since.
If you want to download a copy, or look for more information and more example images, please check out the old HOP website. Some of the information provided might be outdated today though.
The eight images below exist as large scale prints (typically, 150 x 120 cm) and have been part of a number of exhibitions. Please contact me if you are interested in buying a print.
Some of these and a few other HOP images can be seen on my flickr page.
