Here is my "Proof of Concept" assignment as assigned by Mark.
As I said, I started off with a modest goal, and scaled back from there.
I started off doing a Picasa slide show, but realized that Power Point would work better for the combination of text and pictures I wanted to include.
It is a sample of a project for Geometry students, showing their knowledge of various definitions from the first month or so of Geometry. Each slide includes a definition of a geometric term, along with a picture of an everyday object which illustrates the term.
