The earliest known seismographs are found in China. For at least two thousand years, the elaborate bronze sculpture has been used as both a seismic warning system, and identifies the direction and strength of the earthquake. It's ringed by dragons with bronze pearls in their mouths, which drop, ringing, into the mouths of sculpted frogs. Very cool idea.
