the place we held blender conf.au in sydney had a motion capture suit,
which they let me wear (yeah ton im still tring to get the photos :P)
and we had a fun time getting the output into blender. philip had to
write a importer script for the CSM file format. and to even get the CSM
file we had to put the output of the motion capture program into 3D Max.
unfortunatly no one there used blender so i dont think we could get help
from them. but... two teachers from canberra said they could get access
to a motioncapture suit, and im sure they would be up for testing or
something. ill give them an email and see if are up for it.
