I am planning on installing, just a 7" screen with a DVD player with hit. But i also want a screensaver type thing that moves with my music when the music is on? Like the ones on the computer, anyone know how to get this?

 

I don't know a way to do this without a car PC....I have looked at the in dash DVD players, but I can't find any that say they do visualizations with music......probably some lame law that they can't show anything distracting or something.
