I remember playing with imagery like this before it was cool!
Check out the Houston Chronicle's local blog and I highly recommend Kris Alexander's blog. He works emergency management around Austin, Texas and is really sharp even when a hurricane isn't bearing down on him.
The maps at the Perry-Castañeda Library are second to none, SailWX is a good place to track the locations of ships around the globe, Rigzone tracks, you guessed it, oil rigs and the NRL Monterey Marine Meteorology Division has some of the best maps and a catalogue of weather imagery that rivals NOAA's.
