Founder and CEO Jeff Bezos revealed video of the huge project yesterday that's being built inside a West Texas mountain. In a tweet, Bezos said installation has begun on the 500-foot-tall mechanical clock that's designed to tick just once a year.
According to the post, the clock has been in the works for nearly three decades and is the brainchild of inventor Danny Hillis. It's powered by daily thermal cycles and synchronized at solar noon. The century hand advances once every 100 years, and the cuckoo comes out on the millennium.
