That's the Portland Linux/Unix Group
I tried Infinite Painter again, and am still not liking it. The preview for the brush strokes is difficult to see, and completely lies about the size of the stroke. You actually have to paint a stroke to see how big it's going to be. The final straw was when it irrevocably lost a big chunk of one drawing. At that point I gave up and switched back to my old standby of Sketchbook Mobile.
