The 10,000 Year Clock

The Long Now Foundation is building a clock that is supposed to last 10,000 years, and chime with a different song every time it sounds. Danny Hillis invented the clock in 1995, saying

I want to build a clock that ticks once a year. The century hand advances once every 100 years, and the cuckoo comes out on the millennium. I want the cuckoo to come out every millennium for the next 10,000 years.

The 200-foot tall clock will be installed under a Sierra Diablo mountain on Texas land owned by Amazon founder Jeff Bezos. Right now, a robot is carving steps inside the mountain, and some of the larger clock components are being assembled.
