I won't be able to test it for a while as I'm going to be away for
a few days plus am busy with other projects at the moment.

If you want to try goom, with xine-lib 1_beta2 and xine-ui 0.9.17
(or CVS), set gui.visual_anim to "Post Plugin" and gui.post_audio_plugin
to "goom".  Then play an audio-only stream such as an MP3 with xine
using the Xv video output plugin, e.g.:

	xine -V Xv -p foo.mp3

This currently has the weird transposed colors (green and purple),
whereas:

	xine -V Xshm -p foo.mp3

works fine.

It will be great to get this fixed!
