The Golden Rectangle Recursive subdivision of the Golden Rectangle by means of the Golden Ratio -phi- Recursive subdivision of four Golden Rectangles -a Tribute to Piet Mondrian-


On the left-hand side picture, the two rectangles (the big blue and the small red) are similar, hence: 

                     phi        1
                    ----- = ---------
                      1      phi - 1

                       2
                    phi  = phi + 1

The positive root is the Golden Ratio (phi = (1+sqrt(5))/2 = 1,6180339887498949...).
