Vulcan #23

This one has the four-way symmetry, but without the center star.

Nerd talk: (Non-nerds please skip.) The star is still there, it is the little diagonal thorn near the center. First I do the rounded saw Vulcan #21 with a longer, 10x, period. This "copies" the center across the whole plane. Then $z = z^2 / \lvert z \rvert$ creates the four-way (2 axis+2 diagonal) symmetry, with many 'centers'.
