Then I suggest that you focus first on programming a DieMorph


Remember: 'Where Morphic stands out'

The (Morphjic) framework is fully in Smalltalk; there are no
"primitive" widgets or hidden functionality. This means that there are
no restrictions to how a morph will appear and react. There are morphs
that behave like the widgets usually found, and therefore conventional
interfaces can be built. But there are more interesting visual
metaphors like CurveMorph, FishEyeMorph, EnvelopeEditorMorph, or
SpectrumAnalyzerMorph (see the next section with a Squeak at hand to
know them). And the framework is open end extensible. It s not
difficult to make new visual metaphors for our own objects, which are
perfectly integrated in the system.
