An object has identity (can be differentiated from all other objects), responds
to stimuli idiosyncratically, and contains hidden internal state.  OOD is the
process of dividing responsibility among collaborating objects.  See my paper
with Ward Cunningham in OOPSLA '89 (which I am right now missing because of
impending fatherhood- Hi everybody, I miss you).
