The Golden Ratio allows the creation of the Golden Rectangle, which is considered as the most aesthetic and pleasant of all possible rectangles. The Fibonacci sequence is intimately related to that ratio. That is the reason why they have been extensively used to bring Harmony to Art and Architecture. In this paper, we explain how the usage of these proportions leads to the creation of works of art that are pleasant to the spectator. We argue that the usage of these mathematical constructs represents an opportunity for multimedia artists who are interested in novel, better ways to display artistic content to museum audiences.
