Strange Attractor Thinking Putty® has a mind of its own as well. A deep, mysterious black with subtle green sparkles, it comes alive when charged with the included magnet. Strange attractor is the name of a mathematical equation that is commonly part of chaos theory. This equation creates a fractal—a never ending, non-repeating pattern within a dynamic system. Basically, a strange attractor has a mind of its own and creates beautiful patterns in design, art, and nature.
