As a purely dispassionate customer I can certainly state that this product is not just glorified (or inferior) IK! Although the tecnology may not be this, it seems to me that what it does is provide a reasonably universal Easi-pose like function to Poser humanoid figures. William has seemly programmed in anatomically proportionate movement patterns across two or more joint sets to enable easier and anatomically plausible posing. I think the leap of brilliance is creating a system that allows all this to be accessed from a single set of nested parameter dials that can be applied over multiple figure types. It's a simple idea but often the best ones are! As a content developer/ merchant I'm jealous_because I think it results from a good lateral thinking brain and I wish William great success with it. I wouldn't mind betting that you'll find this type of function in the next version of Poser and/or D/S. Of course the programme won't produce Firebirdz quality poses (get real folks!) but it is a great way of starting before the fine tweaking begins!
