    Default Golden Section Rectangle Stereogram

    Rik recently posted a Fibonacci spiral challenge. The spiral is plotted on a golden section rectangle, which I used as the basis for this stereogram. The inward spiral was created by applying Conical fills to each of the squares in the golden section.

    Me either but that's not unusual since I haven't been able to see these for some time now.

    Never give up. You will never fail, but you may find a lot of ways that don't work.

    The lines are the spiral but the background is the square segments of the golden section rectangle. Just try to see the spiral in the lines. It is a lot harder at this small size.

    Normally I'm pretty good at these.
    But, I've not been able to see either of these.

    I used the image for our eyeTricks FB cover https://www.facebook.com/Eyetricks3DStereograms/

    Select the cover image to see it larger and then hover over the top right corner and click on the arrow to see it full size. It might work better at this size.

    What I see is that the rectangles, near the bottom centre recede into the background, like they have been cut and bent back at an angle, with each rectangle going further backwards and at an angle. The spirals follow along on the background - they are not raised above it. Is this correct, Gary?
