This awesome video was featured by Russell McLendon on the Mother Nature Network last week.
It was created by Nicolaus Wegner who captured time-lapse photos of developing thunderstorms in Wyoming and South Dakota last summer, then wove them into a video named Stormscapes. Click on the image to watch it on Vimeo.
After you see it you'll wonder how he lived to tell the tale. Learn more in this National Geographic interview.
