>I've always wanted to stand on an open plain and watch a real tornado, a big twister, from a safe distance. Not likely, but I can still get a thrill with this Tornado Storm Chaser 3D Screensaver. It's a classic tornado scene. In torrential rain, a tornado funnel swirls towards an abandoned farmhouse as debris flies through the air. Thunder claps in the sky as the twisting tornado evokes this dangerous yet beautiful marvel of nature.
