The Long Now in San Francisco

One of the highlights of my recent time in California this autumn was a visit to the Long Now foundation.

These are the chimes of the 10,000 year clock; a clock which should be able to keep an accurate time for the next 10,000 years. It should be maintainable with bronze-age technology, possible to determine operational principles of the clock by close inspection and improvable with time. A real example of long term thinking.
