Man, I have been having a blast with this program lately. Check it out!

Here is an example of what you can do in ArtRage 2:


Basically, I loaded a screenshot. Then, I made a stencil from another painting I did in ArtRage 2. After loading the stencil onto the screenshot, I took the palette knife tool and smeared the screenshot over and around the stencil, creating this effect.

It's so much fun. You can do layers, too. Check out this picture in my subVarience gallery.

If you don't want to pay full price, the free version has quite a few features in it.

I'll see you in the Forest!
