Jean Tinguely is a Swiss sculptor who is famous for his no-purpose kinetic artworks. Heureka one such useless machines.
Tinguely created the Heureka sculpture in 1964 for the Swiss National Exhibition in Lausanne; it was later moved to Zürich. The sculpture is a set of tubes, wheels, forks and other metal details assembled together to create an intricate machine when turned on — or rather, the illusion of one.
