Daisy

A figure resembling a daisy or sunflower in which copies of a geometric figure of increasing size are placed at regular intervals along a spiral. The resulting figure appears to have multiple spirals spreading out from the center.

Note that the logo chosen for the 2006 International Congress of Mathematicians shows a striking similarity to the left figure above.
