Nice image! Not to be picky but it is not actually a spiral -- the 'curves' are concentric circles. The spiral illusion comes from the diagonal line segments across the diamonds...
No, it isn't. But it makes sense to call it spiral, though .
I agree -- that IS how the artist intended it to be interpreted (a sneaky artist, deceiving his audience).
Exactly, and the diamonds on the background is the accomplice. I love the picture as well as the deceptive name, because they remind me to be alert.
