Thank you, DLuders.
dolittle,
I think the program will be the perfect way to tell a story -- or to make a fully functional autonomous robot, in some cases, using finite state machines or behaviour-based systems for control.
As Scratch is aimed at children as young as eight, it'd be difficult for me to aim for a younger group with a harder-to-use program : ) I hope it'll be useful to people as young as nine or ten, and useful to adults as well.
I'm thrilled to hear you think it might be useful to ones to young -- it indicates I'm on the right track!
Cheers,
Clinton
