> Problems we have:
> 1.a good motion tracker patch, only one we have found is the one

> happy to hear about it.
> 2. playing soundfiles, we are looking for a patch to play wav or  
> mp3 or aiff files where we could change the speed, etc. easily.
> 3. And then we are looking some interesting things to alter the
