The Yahoo! Widget Engine (formerly known as Konfabulator) is a JavaScript runtime engine for Windows and Mac OS X 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 WiFi signal strength, will fetch the latest stock quotes for your preferred symbols, and even give your current local weather.

What sets Yahoo! Widget Engine apart from other scripting applications is that it takes full advantage of today's advanced graphics. 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 in Windows XP and Mac OS X.

The format for these Widgets is completely open and easy to learn so creating your own Widgets is an extremely easy task.

For the "skinning" crowd, Yahoo! Widget Engine is a dream come true. You can easily change the look, feel, layout, even functionality of a Widget so that it matches your lifestyle, your desktop, or the pants or skirt you have on that day.
