Water clock at shopping Iguatemi Sao Paulo, Brazil
I took this info at wikipedia: "Only a few modern water clocks exist today. In 1979, French scientist Bernard Gitton began creating his Time-Flow Clocks, which are a modern-day approach to the historical version. His unique glass tube designs can be found in over 30 locations throughout the world, including one at the The Children's Museum of Indianapolis in Indianapolis, Indiana, Shopping Iguatemi in Sao Paulo,Brazil and Shopping Iguatemi in Porto Alegre, Brazil. There are other modern designs of water clocks, including the Royal Gorge water clock in Colorado, the Woodgrove Mall in Nanaimo, British Columbia, and in the Abbotsford Airport in Abbotsford, British Columbia.
Gitton's design relies on gravity powering multiple siphons; for example, after the water level in the minute or hour display tubes is reached, an overflow tube starts to act as a siphon and thus empties the display tube. Actual time keeping is done by a calibrated pendulum powered by a water stream piped from the clock's reservoir. The pendulum has a carefully-constructed container attached to it; this measures the water that is then poured into display system.
Today, the use of water flow to power a clock is a rarely-practiced art, whose purpose is more for show and novelty than for functional accuracy, an example being the Hornsby Water Clock in Sydney, Australia."

| The green colors add a nice touch. The tubes seem to be a little out of focus; I don't know if that's intended or not. |

| Requested comment after voting - hi Lelez - yep, I gave this a five in voting. I think you met the challenge very well - all very straight lines! And I do like the green - not sure what it is but it does add a spark. I think where it lacks a little is it's not quite abstract but it's not quite recognizable either - it is sort of in the middle. So I'm not sure what it is, and it doesn't form enough of a pleasing abstract to stand alone apart from the challenge. Hopefully this helps! |
