The surface wind data in this beautiful wind map from Hint.fm comes from the National Digital Forecast Database. It's basically an art project, not guaranteed to be scientifically perfect, but it's dramatic stuff today during Hurricane Sandy:
These are near-term forecasts, revised once per hour. So what you're seeing is a living portrait. (See the NDFD site for precise details; our timestamp shows time of download.) And for those of you chasing top wind speed, note that maximum speed may occur over lakes or just offshore.
If you're looking for a weather map, or just want more detail on the weather today, see these more traditional maps of temperature and wind.
There's a beautiful animated version, too.

LocalWiki's Philip Neustrom says,
My non-profit, LocalWiki, has been working on this really incredible project to help document the continent of Antarctica. Most notable, at least right now, is this custom map we've pieced together from very-hard-to-find NASA aerial imagery and coastline datasets. It's probably the most beautiful thing I've ever worked on.
Check out the LocalWiki for Antarctica. The project "aims to document the full extent of human involvement on the continent," and for now is focused on a two-mile region surrounding Palmer Station.
