It seems to go without saying that a music player with a beautiful LCD should have some sort of visualization fun while listening to music. Cover flow is nice and all...but for a change of pace... I've see applications like Tune Wiki launch music inside themselves to interact with the music (in this case, display lyrics) but I was curious, from a hypothetical standpoint, is it possible to mess with the iPod's actual music player so that, say, tapping something replaces the album art/track list with a visualization? Or likewise a option to display lyrics (While we're dreaming, karaoke syllable by syllable style) in the music player itself instead of another application? I've done programming myself, so I'm fully aware these things don't just happen and a request isn't going to get done just by the virtue it was requested, but I just wanted to know what was, and wasn't, possible in the current homebrew scene.
