A Useful Widget At Last!

I like the idea of widgets in OS X and the way Dashboard works. However, other than the calculator I don't find myself using them very much. But I finally found a Dashboard widget that really is handy. It's a tool that lets you track packages from a variety of places (Amazon, UPS, FedEx, USPS, etc.). You enter the tracking tag a nice little widget is created. It will change status and will also integrate with Growl to give you notifications (so you don't have to always look at Dashboard to notice a change).

Here's a screenshot.

And a link to the author's (very nice) website. Any widgets that any of my readers use and find useful?
