Curvature Blindness and Rick-Rack

It’s remarkable how this just-published illusion actually illustrates EXACTLY why I couldn’t see what Rick-Rack really was.

All of those lines are just wavy, but the way the colours arrange tell you whether to see them that way, or perceive them as Zigged.

Our Rick-Rack turned out to be no different. It’s just a straight line that is scrunched up for convenience, mating, (or in our case, geometric beauty and fitting). Takahashi Zigged his line visually, we did it with physical materials. Perhaps his way is most elemental, because it is communication in light.

This is monkey-and-stick stuff, in comparison (but more fun I think):

Kate McKinnon Layered Rick Rack

What I learned about fitting zigged things is that lines are just lines, whether wavy, straight or zigged. The little things we do to them (or appear to do to them) aren’t important to their nature.

Finite lines are static moments, little tools of creation, pieces of infinite lines, planes or circles. We use lines here on Earth because we are in a constructed reality and we need static forms like tables, rulers, mathematics. They are all tools to help us measure, build, divide and grow.

Lines work for you: you get to decide what they look like, and what they look like is what work they do in our 3D space.

Read about Takahashi’s simple, glorious discovery here.

Also, a huge Cooper’s Hawk just flew down into my garden, turning a lot of random seed-eating finches into a coherent traveling wave of flight. From the many, into one. Geometry is beautiful!

    link is still leading to an image only, but I found what you wanted to show thanks to your answer to a question above, and saw an animation that shows curves all the time to me. Allow me to think that if Takahashi’s image wouldn’t be so blurr, it would not fool our eyes so easily. But it remains an interesting find.

    This is like geometric poetry.

    Wonderful explanation and beauty of lines. I grasp it and cannot wait to try imagining what I want to make. Thank you

    Are you going to try to duplicate this with black, grey, and white beads?

    The link just took me to the image, not to anything to read. Is there more to it?

    Similar to creating curves from straight lines?
