I think making toys for children is a good idea. There are lots of examples in the physical world that don't progress towards the adult version that are fun and educational. My problem with this is I'm not sure kids would find it fun. Something like HacketyHack that has integrated music and graphics feels like the kind of thing that would make the programs kids want to make. I'd also try Processing.
