Are there any music visualizer apps for the iPad?

I listen to music quite a bit with my iPad when I’m at work, but I miss the visualizer feature that iTunes has on my Mac Pro at home.

I’m looking for an app that will do the same thing, but I don’t want it to have to “hear” the music thru a mic; I want it to integrate with the iPod on the iPad, just like the visualizer in iTunes does.

I checked out iBeams HD and Gravilocity, but it seems like they both have to “hear” thru a mic to respond to audio.

Does anyone know more about these apps or know of one that will do what I want?
