"This site is fantastic. I am regularly looking for media assists using technology to demonstrate some of these topics. If time were no issue, I would have my Geometry students create many of these demos on Cabri Jr. or Sketchpad, but time is always a classroom restriction and your illustrations and animations are first rate. Thank you very much. Thousands of students will benefit from your work. "
