I have been enjoying the hell out of this too.
The bears have come a LONG way, I seriously love that series and have been getting a better understanding of the images you had me look at a while back.
The Persistence of life is fantastic and the one I affectionatly now call the Death of Bob Ross is wonderful.
That last one with the reflection trick is to put it Boston style "frikkin AWESOME"
I think Pixologic had you in mind when they came up with fibermesh.
Cheers Glenn, and keep at it!
