Golden ratio

The golden ratio has been used for hundreds of years by architects and designers to calculate dimensions that are aesthetically pleasing. I am fascinated by this and on many occasions have measured things that appear balanced and pleasing to me to find that they do approximate to this ancient rule of thumb. I often use the ratio for positioning things like pictures or deciding what size of something I want to fill a space. http://en.wikipedia.org/wiki/Golden_ratio
