New stages

[Baegal]

How about:

World Stage
Basically a flat stage, which is the base of the entire stage. However, depending on what song gets played, the stage changes shape and theme. The songs picked are all based on Nintendo songs or third party songs, just to keep it simple.

Anyway, perhaps to make it even interesting, in the background there are three dancers, dancing in sync with the music. While it might be very hard to pull this one off, depending on what music format you use, it might just as well be as easy. When using WAV or MP3, it's common practice to just split the song in small segments of a few beats, mostly four, eight or sixteen.

Don;t know how to pull that off, but that'd be awesome
