Zuzu’s Petals.

I saw a neat image at the dailyminimal tumblr, (greyscale image above)
that got me playing around with these petals. I decided to make the arcs circular, with a control C to move the center, and B to control the angle of the arc. To get the fading effect I included a second slider to do the in between rotations, repeating to get more opaque.
