A guy wants to build a giant clock inside of a mountain. It sounds absurd but it isn't. He wants to make it a pilgrimage site. The clock will run for 10,000 years and will serve to remind people to live for the long-term. His organization is called The Long Now, and he, Stewart Brand, is the founder of the Whole Earth Catalogue, which is where environmentalists and hippies went for their information before the Internet.
Stewart Brand has since done an about-face on several issues that environmentalists frequently don't like: nuclear energy, slums, GM foods, and Geo-engineering, and he has written a book on these things called Whole Earth Discipline. I need to read this. He gave a lecture on some of the subject matter at TED Talks - which, by the way, is a most amazing collection of free, intelligent, and inspirational lectures.
Someday I will make the pilgrimage to that clock!
