The modules supports a large amount of customization. These are some of the things already in the module:
- You can set the background to an image or video
- you can define your own ASCII for the splash
- you can define the colors for most things
- you can set your own border for the window.
- the audio for click, login, logout and ambient can be set
With these you should be able to get a theme close to what your describing.
I could put it on my list of things to look into for specifically defining a splash video. Which is only shown on startup and then would change to the standard background in use now.
