You should read the paper! http://penrose.ink/media/Penrose_SIGGRAPH2020.pdf

They include:

* Vector spaces

* Function diagrams

* Geometric illustrations

* Polygonal meshes

* Ray tracing diagrams

The linked article is pretty much fluff, but the SIGGRAPH paper has the real content.

Already did! Those are all basic examples of those various concepts. How about something that 'mixes metaphors', so to speak? Mathematicians are a creative bunch.

E.g., fuzzy sets. [1] One of the most-cited math papers ever. How could I use Penrose to represent a continuum of grades of membership between sets?
