Thank you so much, your words are bouncing back into my heart as well. I have been working with handicapped kids for a while and what i've always wanted is to give them also the possibility to be equally involved.
I could even imagine many further parts of the story. Animals with different movements and needs, mirroring kids and their characters. The caregiver could say "Hey, let's make the Bob move" and the child would know what he/she means. It is also related to a method for remembering things. The brain is searching for connections, all of the time :)
