The great Rainmeter tool for Windows .

Developers tell us about this open source software:
Rainmeter displays customizable skins, like memory and battery power, RSS feeds and weather forecasts, right on your desktop. Many skins are even functional: they can record your notes and to-do lists, launch your favorite applications, and control your media player - all in a clean, unobtrusive interface that you can rearrange and customize to your liking. Rainmeter is at once an application and a toolkit. You are only limited by your imagination and creativity.
