For what you want to do do, the Squeak Morphic interface is probably
your best friend.
The great benefice of Squeak is to let the user (or teacher) to
combine independent user interface elements (Morph) to create very
specific pedagogical content. Pierre André Dreyfuss and Suzanne
Guyader have created such resources that way. When necessaries these
elements can be programmatically glued together with EToys commands.
See a few examples they are proposing there: http://ofset.org:8000/super/gallery

The next interesting stage in this Smalltalk-o-Morphic paradigm
(=Squeak) is to design additional Morph objects to simulate whatever
you want and then use it in whatever Morphic assemblage you want. This
is what is Kedama for particle, ODECo for gravity.

Related to geometry, I have developed and recently enhanced DrGeoII,
an interactive geometry canvas. You can see from there a screenshot of
such a Morphic geometry canvas used in an Squeak-olpc book
