For those of you seeking a means for your child to be visually creative, may I suggest Artrage 3. I have just been playing with it as it came with the Wacom drawing tablet that I received for Christmas. And let me say, “I love it.”
It is simple, but powerful. You can change pressure settings with a slider which allows one to paint with a normal mouse, or another device used to operate as a mouse. I did use the mouse to do the image below, but I am going to try the mouse technique soon.
