Name This Thing, #5

I'm trying to learn something about lighting as I try to stump you with my choices, but so far it remains as mysterious as some of the puzzles themselves. Mr. S gave me a portable tabletop lighting studio for Christmas and it's a good start at isolating an object and filtering the light, but I don't feel that I actually have any control over the elements yet. I just realized that I may have hit on my real project for this year, which will be learning a little bit about light!
