We built a horizontal circular platform that is actuated from underneath by three speakers. The vibration of the platform causes a small object (e.g., a IC sockets or coins) to act as an hour "hand" on top of the platform to slide around the circular platform, impelled by friction forces due to the vibration. If you bump the hand away, it slowly moves back to the correct hour.
