Here's some serious clockatude, reminding us of the Internets because it's literally a series of tubes, and it's not a big truck. The Canna Clock by ChronArte consists of a dozen glass tubes with 5.25 gallons of water, filling up as time passes and marked at 10-minute increments. For instance, the clock you see here is telling us it's 9:39.
At 12 o'clock noon and midnight, all the water drains down to the bottom, starting the process all over again. It's a river of time. It costs a river of money, too, $12,000 to be exact.
