One of the basic principles of every single art form has to do not with what's there- the music, the words, the movement, the dialogue, the paint - but with what isn't. In the visual arts it's called the 'negative space' - the blank parts around and between objects, which is, ofcourse, every bit as crucial as the objects themselves. The negative space allows us to see the non-negative space in all its glory and gloom, its colour and mystery and light. What isn't there gives what's there meaning. IMAGINE THAT.
