That is great to hear. :)
Also there is projectM-jack:
*http://sourceforge.net/projects/projectm/files/projectM-jack/
<http://sourceforge.net/projects/projectm/files/projectM-jack/>*With jack
audio integrated, that would solve the audio feeding issue, but you
probably also want it to work for the default audio system. Maybe you can
take a look at their code.
Cant wait to try it out, but I am afraid I have to go buy a new disk first
and recover my laptop because my root disk gave in this week. :/ Time for
SSD's.
Will let you know when I can run tests again.

ps: imagine this with different visualizer for different parts of the
sculptures. Hope my video card will hold.
