a pattern to ponder

Not the most challenging challenge ever, but...
Can you work out the shape used to make this pattern?

Obviously more challenging than I first thought!

Unless I am mistaken (which I could very well be) this would be your basic line, so if no one else wants to play here ya go Rik

I hope I am correct.

or, knowing Rik, its could be half that shape mirrored :)

Hi Larry and Steve.

You were just about there Larry, but Steve's hit the nail on the head.

I was looking at how a Fibonacci curve is drawn.
It's not perfect, by the way.
I didn't draw all of the middle starting point.

So, having drawn it, I mirrored it horizontally and then mirrored the two vertically.

Spirals in XXP.
