Collages are used in the circles that composed of this artwork, and we can see various spectacles in each window. The interesting thing in this work is that the screen composed by the circles and dots can be seen as one section, as well as each circle shows different scene and drama. Made as a series in different numbers, each piece of work could be seen as a section that is sliced one by one at different part of a manfs life.
