How Do You Make Something Last 1,000 Years?

http://tomscott.com - http://twitter.com/tomscott - In Trinity Buoy Wharf lighthouse in London -- and a few other science museums around the world -- sits Longplayer, a musical composition designed to last a millennium. How do you keep something running for that long?

Thanks to Rob Blake for holding the camera through the many takes. This one took a while...

And thanks to Martin Deutsch for reminding me about Longplayer!
