The rules say "Any 2D software can be used." But they don't say, "No 3d software can be used." The Poser graphic I saw was less about Poser than about a technique for creating a framework for the graphic, and it could have been easily used for any graphic...photograph or tubes (are tubes of Poser people okay but just not direct renderings?--really, how far does one go with all this before all the enjoyment in trying to create something is completely spoiled?) It will be interesting to see what TPTB have to say about it.
