I agree a 100 percent! Especially with everything that is clearly a geometrical pattern. Will say, a mix of circles/parts of them with other forms such as squares and rectangles, line-cuts between the raw forms etc. etc. There are myriads of combinations possible. And if you just cut one piece more or less you’ll get a different look. If you compare the pattern such as the lower right in your picture from Rubi’s book with some parts in my last picture posted, yes, it looks the same. Or similar. But different. And yes, you will find this very pattern all over the world in all different cultures where humans cut in wood, horn, stone, even metals.
