This is our society. The rectangles are people. Some rectangles are extended to make a base on which a layer is built. Those are artists. They see different, they think different. They do stuff that other people don't. Some people can think that the artists are parasites, that they don't do anything useful. But the artist are beautifying our life, thus making all of us better. The artists (designers are artists in every sense) build their work on layers of work of previous generations.
