Lightning

A cool map of lightning frequency over time across the globe. And a live version for the U.S. Heck, a zoomed-in version on the Northeast for the past 60 minutes. It turns out that you can even buy a small Lightning Detector to map local lightning strikes on your PC. It listens for the signature static crashes from lightning, sometimes called sferics (short for atmospheric noise), much like you can hear on an AM radio during a storm. You can even listen to streaming audio from NASA’s (Alabama) VLF receiver.
