As you may already have discovered, it’s part of the Long Now, which is making the 10,000 Year Clock[0] (about which a friend of mine wrote a play[1], and which helped inspire Neal Stephenson’s sci-fi novel “Anathem”). It involves a bunch of the smartest futurists around, including Stewart Brand (famous for the “Whole Earth Catalog”), Danny Hillis (the Connection Machine), and Brian Eno (producing Talking Heads and U2).
