1. The NYT won a Pulitzer for this story. Really cool.
2. All of time, in a few clicks.
3. The flight deck of Discovery.
4. You need Chrome to look at this one, but it's still neat.
5. Cool documentary about the Cuban Missile Crisis.
6. Rather ordinary profile of Daft Punk commemorating their new album, but with some nifty graphics.
Not sure how much of these things are just gimmicry, but they're worth checking out anyway.
