I attended a talk at Xerox PARC last month where Ken Kahn demonstrated
his programming system "ToonTalk", which was exactly this, with an
animated toolkit full of boxes (for slots/variables), robots who could
be taught actions (methods), etc. It was very impressive, both in
terms of the animation and the choice of metaphors. I don't know what
sort of information about the project exists on the net; is anyone on
this list familiar with it?
