Clock that knocks the time out on a water-filled vase

From Make:

The Sèvres Vase Clock, a design by Georgios Maridakis at the Royal College of Art, taps a vase you already have, every hour, and its tone can be adjusted by varying the amount of water inside.

Knocking clock

Use with a very thin-walled vase for added hourly suspense.

For added fun, drip water into the vase to adjust the pitch each hour.

"I thought it just rang four?"
"No, it's eleven, and we need a new vase and a mop"

@3: I expect it's a proof of concept? The idea itself seems sound, and it could be made into something that looked quite nice.

Finally a clock on BoingBoing that is pure unadulterated awesome.

Only one flaw: You can't buy one. :(
