Inside Sierra Diablo mountains (Texas), is being built the monumental 10,000 Year Clock based upon an idea of Daniel Hillis who in 1995 expressed as follows: "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." Funded by Jeff Bezos, it is designed to run for ten millennia with minimal maintenance and interruption.
