This is an example on juxtaposition. what do you see and think about this picture? would it tell you something... how about if we cut the picture to half.. leaving the " Construction site".. it could be anything.. but how about the whole picture tells? could it be a ground zero? or is it a cleaning site for some bomb experiment..? who knows..
The human brain is created to think and create something extraordinary.. it just got to have a trigger.. and the right terms is juxtaposition.
A tank and a toy bike.. it share the feel of sadness and gloomy..

Juxtaposition is everywhere, done with the intention of bringing out a specific quality or creating an effect, particularly when two contrasting or opposing elements are used. its very important for creative people to think out of the box.. to create something mind blowing.
