I recently got an iPad and as you can see, I'm playing around with the painting apps. This was done with an app called ArtRage. Still a lot to learn, and while it's not an end in itself, it seems a quick way to do sketches and play with color. It's not as precise as a paintbrush, of course, since it's all done on the touchpad. How long has it been since *you* have finger-painted? This is much less messy, of course!
