WebDesktop layers a web browser over your Mac OS X desktop.
Any standard web page can be displayed. WebDesktop uses WebKit, Apple's HTML rendering engine from Safari, so web pages should appear exactly as they do in Safari, including such advanced features as CSS and Flash. But on your desktop.
Bringing WebDesktop to the front allows full interaction with the page, including scrolling, navigation, and form input.
In WebDesktop's preferences, you can specify an automatic refresh interval so that the page on your desktop is reloaded every minute, every 5 minutes, every hour, etc... This is useful for keeping up to date with pages that update frequently.
