A re-enactment of a horror movie perfectly fits the them, I'd say. I bought the Child's Play character from a capsule vending machine for about 2 and a half USD. Immediately I had this image in mind thinking about my attic diorama. I wanted warm light coming from the floor below and cool light streaming in through the skylights left and behind. I added the second character with a scared expression on his face, used a fog machine to create a dusty atmosphere and to show the light. That is it.
