"Squeak Version 2 includes sketches of two entire
end-user programming paradigms, integrated with the morphic environment.
One is a wiring metaphor inspired by Fabrik,
which allows simple component assembly to be performed the way you put
a stereo system together. The implementation is just a toy (no real dataflow
model or encapsulation yet) but you may enjoy the demonstration in Play
With Me - 6.
The other is a tile-based interface that offers
viewers and scriptors as iconic and active counterparts to Squeak's textual
and more passive inspectors and browsers. It has been taken fairly far
in a number of directions, as you may discover by following the introductory
tour: Programming in
Morphic."
