First of all, I want to apologize for the sound quality of this video. The computer it was recorded on has a terrible microphone.
Also, there are some references that got left out of the video so I wanted to add them here.
All of the animations were made using GoAnimate.com
Geometer’s Sketchpad was used for the animated math graphics. Each activity was a free download from http://sketchexchange.keypress.com/sketch/view/574/3d-invisibility-toolkit and http://sketchexchange.keypress.com/sketch/view/577/3d-gallery
The photo of John Keller was borrowed from his website http://www.arcsmodel.com/
