How to make this circles

Hi people, i need some help, iam geting started in vvvv and i want to know how can a make this kind of circle http://z.about.com/d/christianity/1/0/b/2/Christian_Circle.png . thanks for any help.

Hi,
A quad with a transparent png texture applied on it seems the most convenient way…But you can also have a look at the Segment(DX9) node which allows to draw circles by handling the resolution input pin to a higher value, and have a dynamic influence on cycle and inner radius.

thanks for your replay, i will try your advice.
