Hands down the most interesting thing on the internet.
You can watch the trailer, but it doesn't do it justice and doesn't prepare you for the fact that you're about to spend an hour on the site. It's fascinating, thoughtful, engrossing, interactive, beautifully produced, moving. I haven't seen anything like it before. Just do yourself a favor and set aside some time to click the darned link!
