Double Celtic Spiral

More work in Inkscape with help from a David James and Vitor Gonzalez book. I up loaded both the ping and the svg file.

I used the following tools in Inkscape.

Spiral
Ellipse
Bucket
Bezier
Clone

I've discovered that Inkscape can make really nice double spirals with the spiral tool and clone that is flipped on both the horizontal and vertical axis. The math guys out there will know this as symmetry about the origin. But, I digress.
