Morphic is a direct-manipulation User Interface (UI) construction kit based on display trees. It works with graphical objects called Morphs. It replaces the original Model View Controller graphics toolkit of Smalltalk-80.
How Morphic works
The UI process repeatedly calls World doOneCycle. It uses the ActiveHand (instance of HandMorph).
