The layout isn't bad, in my opinion. We could do with some prettier buttons, but those will do for now. But I can't stand that banana. I mean, really, does anyone not get bored with it anymore?
However, you bring up a good point--this window offers a great opportunity to put in one of your favourite little animations to dance around. For example, I could easily live with this little girl:

That's right..dance dance. You can even pretend they're dancing to the beat, even though they're really just mindlessly cycling through a series of frames. You could also attempt to make some pretty swirls, ala Winamp:
Sure, it's not really an AVS Preset, but it can be just as seizure-inducing!
I really am serious about this, though, I'd love to see some of these translated to .tga so it could be played in the window, especially the first one. I'd do it myself, but i'm a lazy d0rf, and don't altogether know how. Anyone? Anyone? Bueller? Bueller?
