Konfabulator is a JavaScript runtime engine that lets you run little files called Widgets that can do pretty much whatever you want them to. Widgets can be alarm clocks, calculators, can tell you your AirPort signal strength, will fetch the latest stock quotes for your preferred symbols, and even give your current local weather.
What sets Konfabulator apart from other scripting applications is that it takes full advantage rendering. This allows Widgets to blend fluidly into your desktop without the constraints of traditional window borders. Toss in some sliding and fading, and these little guys are right at home on your desktop.
