1.)Probably get some new space ghost images.

2.)Figure out a way to get rid of flicker, perhaps use gdk_pixbuf function for
drawing, but I'm not sure what a GdkDrawable is, can I just have a window the
correct size and draw straight to it?

3.)Could take advantage of using gdk-pixbuf and do things like have an option to scale themes to certain size, could even scale it down enough to fit it in the visualization part of the xmms window, but that'd be too small and would probably look stupid.

4.)Port to windows

5.)Possibly turn gdancer into a standalone app and have it monitor sound going
through esound or something.  That way you could use it with any sound program. 

Thoughts on any of these items, or ideas of things to add are welcome.
