I've found exactly the opposite--the MVC paradigm works great in
Morphic. It was the first way I learned to do graphics in Smalltalk,
and I used it for several projects. The occasional times I've looked at
the implementation (ie, the "pluggable" morphs), the code has
seemed quite natural and straightforward.
The most interesting philosophical difference I've noticed between
Morphic and MVC, is that a Morph is never in full control of the UI.
This is different from MVC, where the Controllers all take turns running
