This chaotic pendulum was invented by Professor Nicolas Rott (Federal Institute of Technology, Zürich, Switzerland) in 1970. It consists of fixed and flexible elements in anodised red steel which, once activated, move in extraordinary and unpredictable ways around the fixed metal axis, often even reversing direction. For mounting on a wall.
