Windows/Mac (Adobe AIR): Desktop widget application Snippage displays snipped portions of web pages as widgets on your desktop, so you can keep your eye on your to-do list, email or anything you'd like.
Once you've installed the application, you can create a snip of a page by expanding the widget to full-size view, browsing to the site you want to snip, and then just positioning the square over the portion you'd like to see. Click the scissors icon, and you'll have a widget that you can place anywhere on your desktop. You can create multiple snips and put them wherever you'd like, set the links to open in a new window, and even disable automatic page refreshing if you choose.
The widget toolbar will auto-hide once you've switched focus to something else, so they appear to be sitting right on the desktop background — it's a great way to put your web-based to-do list on your desktop, especially for XP users that miss the Active Desktop feature that was removed in Windows 7 and Vista. Snippage is a free download for Windows and Mac, requires the Adobe AIR platform.
