Thanks for all the pointers to concept maps. Its impressive how many
options exist. I can see how they fit well with Piaget and other
However, my immediate challenge is figure out what it will take to
support cmap tools on the XO.
Has anyone tried making the activity which is X-windows and inside which
other activities can run?
Any other ideas on how to make an app which uses multiple windows (and I
believe allows drag and drop of data from one to the other) work on the XO?
