Clocks come in many shapes and sizes. There are the grand old clocks found in European city-centers, the incredible gas-powered Atmos clocks, and of course the ubiquitous electronic clocks that glow from myriad devices throughout our homes. There's even a clock being built in a Texas mountain that's meant to keep time for 10,000 years. But what we have here today is something a little bit different.
