The goal was to make a light box for my students to use that didn't cost me an arm and a leg. Went to the second-hand store and found a florescent light... ($4.99 with 50% off) then noticed a suitcase/briefcase ($3.99 with 50% off). I got them both and started thinking of ways to put them together.
4/2016: My daughter still uses this. Works great. Someday I will make another one.
