This is weird...a movie of me creating the applet for this post. Pat Ballew asked me how to do this.

The ability to do this easily is what attracted me to GeoGebra almost four years ago. I started out using Cabri on the old TI Voyage 200, then moved to Sketchpad because my school had a site license (which meant my students could actually buy the software foe something like $25). One man's opinion, but GeoGebra is just better. There is no site license to purchase (which means my students can use the software for something like FREE). I look at the new features in the current version of GSP, and it is a good program, but they are playing catch-up. GeoGebra has set the bar HIGH with respect to dynamic mathematics software.
