The original Alice was implemented in C and Python, with user scripts
written in a case-insensitive variant of Python. That Alice core was
ported to Squeak (called "Wonderland", using the Balloon3D graphics
engine). This was never officially part of the Alice project, but of
course the Alice and Squeak folks regularly exchanged ideas.
Alice 2.0 is implemented in Java. User scripts were not written in
Java but using tile-scripts (similar to Etoys). You can turn on a
switch to show punctuation on tiles to make it look more like a
Now Alice 3.0 is going to expose Java programming directly, to appeal
to CS1 courses.
