I want a simple analog wall clock to be programmed to stop working properly once an hour. I want the second hand to start skipping seconds and moving backwards and then spinning around in a circle. I want the clock to seem broken for roughly one minute before acting normally again until the next hour. The clock does not need to keep time.
I am a mechanical engineer with good knowledge of various types of mechanisms and couplings. I have understanding how a watch works and have good problem solving skills. Given time i can complete this project with ease. In what form do you require the idea?
