Readers in San Francisco have the opportunity tomorrow to hear Worldchanging Chairman Ed Burtynsky deliver a Long Now Seminar. Ed will be talking about his ideas for long-term intergenerational communication through art:

There should be a gallery that collects, displays, and sifts such works over centuries and millennia, and develops ways to preserve them. That is exactly Burtynsky's plan--- a 10,000-year Gallery to accompany the 10,000-year Clock. His presentation will explore and demonstrate the idea.

I'd bet this is going to be a hell of an interesting talk.

It's at the Fort Mason Center, it's $10, and the details can be found on the Long Now site.
