Now that the 21st century has recently arrived I think it is time to liven up economics classes by animating the diagrams. Just in case students are tired of teachers who rub 2 rocks together (aka chalk and blackboards) or point to (and sometimes scribble all over) same old same old diagrams.
So I offer this collection which I'm using in the AP Micro classes I teach.
There didn't seem to be much out there. (I also teach AP Calculus BC but it is already well-served by the GeoGebra community)
