Quick something-interesting

Something twigged when I was typing up notes, and I was able to track it down after a bit of messing around with google. I present to you:

The Clock of the Long Now, an attempt to make a clock that will be able to tell time for 10,000 years. It's actually very, very difficult to make something that will last that long without human intervention.

It's a really interesting read. The entire project, the Long Now Foundation, is really interesting in general.
