This is so cool. Just the kind of thing we have now come to expect from the mega-brilliant Bezos.
This, though it will cost him $42 million, is NOT even petty cash to him these days — Amazon stock is doing so well. The total cost to build this giant clock is more, but Jeff, with his $42M is the largest benefactor.
Appears that they have been talking about such a clock since 1984. A prototype for this clock, built in 1999, is now on display at the Science Museum in London.
