Prototype Clock of the Long Now

This clock is the first prototype of the Clock of the Long Now, built in 1999:

Clock of the Long Now in the London Science Museum

Construction of the final version of this clock has not started yet, but here is some information about the plans for the clock:

• It will be housed underground in Mount Washington, Nevada, Texas
• It will be mechanical
• It will tick once a year
• The century hand will advance once every hundred years
  
• A cuckoo will come out every millennium
• It will synchronise with the midday sun to keep it accurate
• And it will run for 10000 years (and be maintainable by future generations)
  

The purpose of the clock is to 'promote long term thinking'. Individuals, companies and governments are being encouraged by the Long Now Foundation not to only plan for the short term but also for the long term - as long as 10000 years!
