I have written in the past about my love of fractals and always welcome the chance to illustrate my latest find. I ran into this YouTube video that is simply amazing and could not resist showing it. The complexity of such simplicity is amazing. Keep in mind as you watch the figures flow that each movement is a mathematical formula that is ever shifting.
I stumbled upon it while looking for something else (isn't that always the way) and was taken by the work involved . I think you will be too.
