I don't know if this info has been posted here before. If so, I
apologize.
Tasa Graphic Arts has 3 interactive cdroms of interest to maps-l folks:
Introduction to Topographic Maps--$59
Explore the Planets--$59
The Theory of Plate Tectonics--$59
These are designed for 7th grade to college.
I have seen the Plate Tectonics one. It is very well done. It also has
its text in Spanish.
They are worth checking out.
