MyCastScreen is the first custom home screen replacement application for Google Chromecast. It doesn't actually replace your home screen - as that's not actually possible (yet) - but you can cast this screen, close the app, and go on with your day. It remembers your settings and starts up with the previous session's settings so you won't have to update the options every time.

* Enter a custom RSS feed URL to see your personalized news feed tick by.
* Upload an image to the internet and input the URL for a custom home screen wallpaper image
