Rainmeter is similar to Window’s Gadgets, Macintosh’s Widgets and Google Desktop in that way that you can add stuff to your Windows desktop. Stuff like a clock, RSS-readers, system information, calendar, weather information, e-mails, etc. There are more ways to customize your desktop with Rainmeter than it is with the applications I mentioned above, and there is a huge amount of whole suits and small apps that you can download to extend Rainmeter.
I recommend you all to download and try out this application. It adds so much to your desktop and many of the available suits looks really cool. The only downside is that if you have a lot of stuff in Rainmeter that refreshes very often, it can consume a lot of CPU-power. (Links just below the images)
