This may be at an angle to what you want to do, but I've been playing 
with Boxer lately, as a result of reading  diSessa's book "Changing 
Minds" a few weeks ago.  The whole point of Boxer and Logo before it 
is to provide a way for schoolchildren to learn about computing by 
doing it, and many of the techniques they use should be adaptable to 
EToys.  You might get some ideas for workshop projects from the 
teaching projects that have been developed for these languages.  Try 
the following sites as a start



It shouldn't be hard to write a Logo or Boxer interpreter for Squeak, 
in fact, I've been wondering how difficult it would be to write a 
BoxerMorph as a Project subclass, so you would have an entire Boxer 
environment built on Squeak.  It's on my list to look into soon.
