<<I've had students in arm casts
paint some beautiful cubistic paintings. We attached a stick to the cast and
a paintbrush to the stick and away they went by standing and painting on
paper on the floor.>>
We talked about this and painting might be a possibility in a week or so. Right now he's still dealing with quite a bit of pain when he moves his arm. I was surprised to see him opting to use his left hand today on the computer because his right arm was still too uncomfortable to move around much.
He's an interesting, detail-oriented kid. While it might be good to get him to "loosen up" a bit with painting, it might also drive him crazy, as he likes to be pretty precise!
We're both going to brainstorm over the weekend to see what we can come up with. I'll approach him again about trying some "experimental" stuff and will see what he says re: painting with his feet, opposite hand--or mouth!
