On 1999/04/04 the Golden Ratio (or Divine Proportion) = Phi = (sqr(5) + 1) / 2 was introduced. If you multiply the angle Alfa in the program by Phi in each iteration, you can obtain curving figures like the one below. (This one can’t be obtained with the current version of the MSDOS program “arbol209.zip” nor with the Java applet.)
Mathematics, Fibonacci, Design Oh yeah, more of that 1.618 stuff. Ratio Divine in time for holiday present shaping.
