Is this just a normal spiral? How about a fibonacci spiral?
Yes it's a normal spiral; the ratio is constant. Doing an approximation to a fibonacci spiral should be a minor tweak, the ratio just changes: eg in the example on that page the ratios are [8%5, 5%3, 3%2 ...]. The final result will only be an approximation since the aspect ratio of the screen will vary, so we'll probably get rectangles rather than squares. I'll code this up later in the week. - Joe
