Thanks for all the ideas, I will look into a lot of them. I think trying something with graphic arts is a good idea. DS has fine motor issues so doesn't play with things like legos the way I had hoped. DD is very good with them, just doesn't seem to have the interest for whatever reason. Maybe it's too much sorting through little pieces trying to find what you need. DS was surprisingly good at with building his robots at robotics camp. I think he was the youngest one there and was able to use tiny little screws and parts. So maybe it will take some work but be ultimately doable.
