These things are very cool. Total atmospheric "precipitable water" (i.e. water suspended in the air) above each ocean point, presented by Univ of Wisconsin.
It's animated – click on it.
I found them here, after following a link from xkcd – of course (see previous [broken link! FIXME] post).
I thought it would be a short-lived joke, when I landed on the recent xkcd cartoon and it said, in the pop-up text, "click and drag."
I cluck and drug. And cluck and drug. And 30 minutes later I was still clicking and dragging. Very entertaining. Follow the link – it doesn't embed very well.
My favorite gem: after scrolling down and down and down and down there were these people trapped in a hole. They were hoping someone would friend them on facebook or twitter.
