DisplayFusion - great free tool for multiple monitors

Not .Net specific but great if you have multiple monitors for coding (and if you don't then I recommend it). From the site : "DisplayFusion is a fantastic (and free) new application that can make your dual monitor (or triple monitor or more) life much, much easier! From allowing you to use a different wallpaper on each monitor, to integrating with Flickr for image searching, to providing hotkeys for managing your application windows."
