Tim, I am also part of a group that has a weekly challenge. Someone gets picked as having the "best", and that person picks the next challenge. I think it makes things somewhat creative, but then again, you get stuff like snow, mountains, children, and a few others some of us don't see/have, etc.

I do like the idea of interpretations of feelings, emotions, colors, and themes like pride, power, etc., as opposed to just sunsets.
