There are a few options to have a home screen image and ways to set the system so it is always on. As for a screensaver, there is no way to use a standard screensaver file but there might be other ways to accomplish this. Can you explain a little more about what you are looking to do and what how you want the screens to behave when inactive?
I wanted to add our schools logo for an image (or if the screensaver existed it would be animated) I want it to have a 3 minute idle time and after that it would show the schools logo. When the screen with the logo on it is clicked, it would show all of the lighting things.
This is doable but will require working with an ETC dealer or Service provider to make the configuration changes. You can find a local provider here www.etcconnect.com/Find-A-Dealer.aspx
