You work in any idea and try to obtain a result but the result is really different. One day i go to one of my favorite place to take a wild's ducs pics. I have a real submarine on te right and the city with cars on the left and a lot of cloud with rain and the result are so different of what i have think : "drought" pic in my gallery. A contest like that! with any idea but with accidental bigger result!
Insanity... now THAT would be interesting to see. Uh...
How about the concept of Evil. But not just straight out evil, i guess like a thing to "finding the evil in everyone" sort of thing. What I'm trying to say is do a contest that captures the concept that there is an evil side in everyone.
