An example of an alternative GUI was Andreas Raab's "Tweak", which was
used in the Croquet and Sophie projects.

I am not sure why this didn't become an option in the standard Squeak
distribution.

Another GUI for Squeak was PenSprites implemented at Disney. It was a
fraction of the size of Morphic meant for resource constrained devices.
That remained internal to Disney.

About MVC and Morphic, you have to remember that Squeak was created to
implement EToys. EToys projects can have several things active on the
screen at the same time while MVC is about switching focus between
objects on the screen as the user interacts with them. If you start a
fish swimming in circles in one corner of the screen you don't want it
to freeze up if you start a new drawing in another corner.
