Fabulous!! I love this sort of thing. Sometimes I sort of doodle a bit. But I usually get impatient with it and take it to the computer and say, "Here, repeat this line, this way. Okay, Here, repeat this perfect circle I made with your tools." And it usually behaves pretty well. Lol

I'm not sure it really saves my hands so much as it saves me from my internal doodle critic that says, "You're getting it all wrong. It's not balanced. It's outta kilter ... " ... Yes for real my doodles have a critic. Go figure.
