This post isn't really project related but I thought I'd post a paragraph about a slick little applet application that is cross platform (Windows and Mac) and free!
From their website:
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 Konfabulator 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.
