Imagery Analysis - it sounds boring, but this quiz I found is kind of fun.
I took it the other day when I got sidetracked trying to write a paper on GIS and imagery analysis for humanitarian response. (It was riveting, believe me.) I discovered that I have a hidden talent for imagery analysis, so now I know what to do with myself if the whole foreign service thing doesn't work out.
