Fine Arts and Art Installation Design Relativity Temporal Clock by Liang-jiun Chiu Relativity might be the solution to the annoyance of having a time perception that does not fit the physical world. This machine adjusts time perception of the user through a method related to hypnosis. The clock on the machine is driven by a stirling engine at an unstable speed according to the unstable heat of the fire source, making a series of metal clinking sound to reset the time perception of the user and give a more proper one. Thus, the user can have a sense of time that fits the current scenario.
