This is a time-lapse of a gravity wave taken by the Tama, Iowa KCCI-TV webcam on 6 May 2007. Gravity waves form when buoyancy pushes air up, and gravity pulls it back down. Very cool stuff!

favorite timelapses, from any source.
"timelapse" means the camera records images at regular intervals, so the change in a moving subject appears accelerated or compressed.
lots of these show the natural world (storms, astronomy, animals), but some of the most interesting are mechanical or technology-related.
