Been playing with the golden mean lately. Got some new ones for ya. 1.618, 10, 1.618,. And if you've got infinite time and nothing to do, try waiting for this to complete: 3.14159, 10, 1.618
3.14159 10 3.14159 This is the longest, yet most intricate design i have seen, but after plating with pi for a while i think it's one of the coolest ones to watch complete itself.
