Scribble
I think this is one of the best free drawing applications that I have checked out so far. I love the “SAVE” feature (see review on “Whiteboard”), the ability to draw on other pictures and a pretty good selection of colours. I think it would be fantastic if you could mix colours or somehow pick the exact colour you want. The only thing I would change is the ability to hide the tool bar at the bottom while drawing.
