How sophisticated are the mats you are putting together? Lots of added color, or just the same settings with different texture references? I have a very crude program that I was working on that makes these mat poses very easy. Unfortunately, I decided to start a Python version, and stopped working on the original (never actually started on the python version...) if you have a PC, and are interested, send me your email address via 'rosity IM and I'll see if I can't work the details out for getting you access to it. eric
