GDE is a very feature rich theme for your Samsung Captivate. Instead of calling it a theme, we can call it an app that alters the front end of you Android app to some extent. It gives you a desktop cube, something you see on Linux computers. And stretch and fading transitions. You can scroll endlessly. This is kind of fun to do all this on a phone. You even get a custom application dock widget. And you also get something called as the conversation widget. To drag the widget, you just have to use the outermost right or left corners of your phone. Click here to download GDE theme for your Samsung Captivate.
