Mathmos - Virtual Lava Lamp

Molten globs of whatever that stuff is that goes in a lava lamp float up your screen, just like in a real lava lamp. Mathmos have done a really nice job here. The web page detects if you are on a Mac or a PC and presents the right screensaver. There is also a Settings window to change the color, shading and quantity of lava.
