Thanks for the tip, but I have Painter X and I'm sure that Deep Paint can't hold a candle to it (it isn't free however).  There was a painting program that e-frontier was giving away with their Content Paradise collections--I'm not sure what it was called though.

I'd be interested if the 3D version were available for free.  I wish Corel would come out with a 3D version of Painter that actually worked (the old Painter 3D by Metacreations had series bugs that were difficult to work around).  Now that Photoshop has some 3D abilities I'm hoping that will spur Corel to get with the program.
