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.

These images exist as large scale prints (typically, 150 x 120 cm) and have been part of a number of exhibitions.

Based on Gumowski-Mira images, I also created algorithmic music (http://www.michaelpeters.de/projects/impossible-music)
