The humble window is one of the most brilliant and most functional inventions ever devised by humankind. We don't think about windows often, but the truth is that they are huge parts of our lives. Windows influence how we feel about the architecture, shape, and appearance of a building, as well as change our opinions of the company or people housed inside that building. Windows can make us feel comfortable and satisfied or inexplicably dissatisfied, depending on how and where they are placed. Windows can even help to change our outlook on the world--both literally and metaphorically.
