Desktopr is simple way to extend your desktop with any content you can even imagine. It allows you to set any website, Quartz composition, Flash movie, or other content as your desktop background.
Imagine your Facebook, Gmail, Twitter or favorite blog or magazine as a background of your desktop. You can switch currently displayed content from desktop level to front anytime from the menu bar, and start browsing immediately. All content items (websites / animations / movies / etc.) are easily configured and for all of them, may be set for a specific duration from 10 seconds to unlimited. Count of content items is unlimited.
Youtube and Vimeo movies are played in full-screen automatically (optional). Flash or other plugins can be optionally disabled.
