The monumental installation of a Four-Quadrant Time Machine followed at Baselworld 2015, which stood in the inner courtyard of the famous watch and clock fair.
Its five meters size was big enough to walk through, inviting the visitor to listen to the magical sound of four identical but non-synchronous Time Machines.
The visitor could also watch the movement of 24 wheels rotating steadily, with only the anchor wheels being stopped and released by the pendulum.
