The artwork is an attempt to show - How although there are limitless things to think about , how we are stuck to just looking into the 'cube' which is a way to portray something definite . All this is happening in one section of the dudes head who is almost out of his senses. His shirt has vertical stripes which is an indirect way of showing the costume of a prisoner and how he is trapped with the thinkings of the society. Tilt the canvas a little and you may be able to see the bird wearing the hat , trying to say how it's freedom is a 100 times yours.
