(1/?) Patterned Penrose Pentagon thread

I submitted this picture to the 2021 JMM Art Exhibition with the following description:

‘This year, Sir Roger Penrose won a Nobel Prize in physics for his work involving black holes. This piece is intended to be a general celebration of his work.

It consists of an impossible shape referred to as the Penrose Pentagon, which appears to be patterned with an Penrose rhombus tiling. In actuality, the tiling has been done over a large area, but is only visible through the strategically-aligned impossible shape, with shading providing the illusion of depth.

Last year the “shadow” of black hole at the center of galaxy M87 was “photographed” using the Event Horizon Telescope. Strangely enough, one can almost see a pentagon there. I have used a similar colour palette to tint this pentagon.’

50-somethings, it's Altair designs! I was looking at Penrose tilings and getting flashbacks to being 8 again with a new pack of felt-tips and those gorgeous geometric designs, and could not remember the name of the drawing pads. A win. Thank you to all who rushed to fill the lacuna.

One more for today, also partly as a self-reminder to use hashtags. This is a single-armed spiral based on Marjorie Rice's "pentagonal versatile". I'm not sure this particular arrangement has been seen before.

I made this a few years ago. I am posting it today in honour of Sir Roger Penrose’s birthday.

“Cairo Transitions: Radial”

Does this look like a to you? Or could it be a of trapezoids and triangles?

More from the investigation of animation on a grid. What do you see?

I was working on these because of the prompt from @csk a couple of years ago.

Another -on-a-grid clip. This one looks at the irregular pentagons moving around.
