There are Penrose Tiles named after Roger Penrose. Those are seamless repeatable Tiles. They appear to have been found in some Historical sites.

So what?

Friendly as usual.
I remember those tiles from when I was into DIY stuff.

Thanks. I have learnt something new today :)

A picture is supposed to be worth several words!

Did you mean to provide a photo to go along with the text?

I had a lot of fun when I discovered Penrose tiling quite some years ago...
Sun and cartwheel - created in SketchUp. Unfortunately the image export is basically just a screenshot so fine detail is lost.
[Edit] If you look closely in the sun pattern, the kite and dart shapes are repeated in the same pattern on a larger scale. This repetition is itself repeated as the tiling grows bigger and bigger.

Mathematically I found it interesting.

How does saving Draft work in DPRevived?

No idea. I didn't know you could. Do you mean 'Preview'?

I misunderstood. I thought I could from Mobile go to my Mac saved as “Draft” and the unsent text from my phone would appear but it’s not possible to do it.
What’s on Mobile (or Desktop) stays on their devices. Only after sending is it seen by everyone.

Veritasium has a video on the Penrose Tiles.
