On my page for [The Sensible Calculus Book](http://users.humboldt.edu/flashman/senscalca_x.html) you will find how I've added SAGE to this page- with interacts for graphs and one of the mapping diagram interacts I am developing from the assistance of Jeff Denny, Jason Grout, and others at Sage 5 Edu.
ALSO- I have a new demo using Geogebra on the same page to do similar things with graphs and mapping diagrams dynamically. Is there some way to have Geogebra and SAGE interact?
