What kind of message would an object have that more clearly states what’s going on? Think of a shadow as a graphic expression.
Make a drawing or edit a photograph to include a shadow in the shape of the object that expresses a message about it.

Image from The Tap Tavern bearing no attribution (sad face). Found via Amy Burvall’s Google+ Image is Everything community, too lacking attribution. Sigh. Maybe a shadow message is needed.
