The massive marvels of architecture constantly take various forms around us. Every day, we are surrounded by a multitude of buildings, bridges and roads that prove the importance of architects and engineers. There is an element of artistry that accompanies the ability to create such designs. For example, have you ever seen a stained-glass window? They are beautiful, colourful and may even depict important scenes. They also have another interesting quality. A stained-glass window has the ability to change the colour of any light that passes through it. This means that something as small as a window has complete control over the atmosphere that is created within a building. There is, of course, much to learn from this fact.
