@tinribbs@mothermalarky oh thank you for noticing the layers and that it is squared (almost), I spent what seemed like ages moving the camera just a fraction to get it right....got some interesting looks!
Such an interesting picture. I have looked at it several times and see something new in it each time I have looked. So much detail in all the lines and shapes.
There really is so much detail here - those lines are terrific - reminds me of when I taught and we'd ask the kids to count the number of parallel lines or rectangles - this would have made a fantastic exercise!
