Hi Dave,
Thank you for taking the time to look at BabyIDE. You spotted its most 
novel part, the graphical
interaction diagram. Alan coined the term object orientation: "/Thus its 
semantics are a bit like having thousands and thousands of computers all 
hooked together by a very fast network./". The interaction diagram shows 
such a network where objects have been mustered to play their roles in 
the performance of a task or use case. The behavior of the objects is 
coded in methods attached to the roles.

General questions and ideas about DCI can best be placed on
         object-composition at googlegroups.com
which represents several years of DCI knowledge and experience with 
implementations in languages such as C++, C#, Marvin, Ruby, Scala, 
Erlang, Javascript, Haxe, PHP, and Python. Smalltalk is not in this 
list. This is surprising since Smalltalk has the most sophisticated IDE 
for DCI and is its natural home.

The essence of object orientation is that
objects collaborateto achieve a goal.
