The simplicity of this Timing Chain Clock is great. The large chain is slung over a sprocket, gravity pulls the chain loop downwards. A geared motor is used to slowly turn the chain to display the time using the acrylic laser cut numbers. Unfortunately Henry Stafford has sold the clock but notes that he will be building more in the future. I think having 3 of these side by side showing hours, first digit of minutes and the second digit of the minutes would be a cool upgrade to the idea.
