I was inspired to draw this sketch showing depth by the view out of a window next to our classroom (if you exit the classroom and turn left, there is window that has a similar view). I tried to draw this so that it created a sense of depth through repetition of smaller and smaller squares. There are also supposed to be pillars in between each wall, but I don't think they came out quite as obvious. I also placed the final window on the right third of page so that I was following the rule of thirds. Personally, I thought it helped create some visual motion to the pattern. Since the pattern leans to the right, it creates some energy. I don't think the same amount of energy would have existed had I put the last wall in the center of the page.
