That's pretty cool. Thanks for sharing

The blurb on the home page is pretty interesting.....

This is the collaboration site of Fernanda Viégas and Martin Wattenberg. We invent new ways for people to think and talk about data.
As technologists we ask, Can visualization help people think collectively? Can visualization move beyond numbers into the realm of words and images?

As artists we seek the joy of revelation. Can visualization tell never-before-told stories? Can it uncover truths about color, memory, and sensuality?

I would love a little explanation of what we're looking at beyond the obvious.  I found this:

The winding currents of our atmosphere have never been easier to appreciate thanks to a new visualization project by Google computer scientists. Browse on over to hint.fm/wind and watch our nation’s streams of flow converge, diverge, accelerate and decelerate as they create our weather.

The visualization uses data from the National Weather Service to refresh hourly.
