The idea is to a collection of random metal shapes suspended in the area in from of a backdrop and have a sun in the distance move
and shine on the random metal pieces, that will creature an image with their shadows.
The perspective will be at an angle like in the image above it will have a small floor and wall acting as a background and canvas for shadows. Abstract shapes will be placed and suspended in the air adjacent to the wall, behind the camera will be some diffuse lighting that will shine on the abstract shapes making the image of a chicken in simplistic fashion. There will also be slight aninmation of the camera moving, not much movement but enough to show that from a specific angle the shadows make an image and from another it doesn't.
First screenshot - working on
