On a side note, googleing granny leads to weird results, we live in strange times.
Granny 3D is a costly professional tool, Chirmaya has made an impressive job, but making a 3D model and animating it would need a LOT of work. I don't think that any community can do that.
On a somewhat related note.... I had wondered how much, if any, extra mileage we could get out of existing models. For instance, could we simply scale up some of the minion models and *poof* now you have a potential model for a minotaur / wizard / archer DG?
I am pretty sure it would be the only realistic way to create a new demigod, but we would'nt be able to create a lot of them this way, there are not so many different minions.
