Tempest! Art of Nature brings you shockingly beautiful lightning video from around the world.

Tempest! is great for those who don’t want a CPU hungry screensaver running all the time but instead appreciate a gentle artistic reminder from time to time that the machine is still awake. Tempest! runs cool because your CPU rests between lightning strikes.

For best results use a large screen in a dark room. Thunder and rain have been added by popular request. Some people find Tempest! an aid to a meditative state of mind.

"A gem of the Mac App Store" ~

A separate screensaver launcher can be downloaded from the "View" menu in the app.

If you have old Quicktime components on your computer, they can interfere with video playback of this and all other video apps on the Mac App Store, there is a free app on the store called SandboxCleaner that can check your system for this.
