Minsky is an inspiration, not a blueprint. To quote from AI Lab Memo 306 ("the 
Frame paper"), "I try here to bring together several of these issues by 
pretending to have a unified, coherent theory." Other inspirations include 
cybernetics and evolutionary psychology. 

The Lego blocks model breaks down because the modules or Minsky's agents do in 
fact occur at high levels of abstraction. But the high-level ones operate by 
telling low-level ones what to do and by using their pre-digested 
interpretations of what's going on. Internally they are just as simple as the 
low-level ones.

I would be reasonably happy identifying a concept and a module as I've been 
using the term. At the moment I'm working with the assumption that my modules 
need to split when they try to model a non-holonomic system, but that will 
depend on a LOT of experimentation I haven't done yet.
