I was about to comment that I also made a small LED panel, but then realized it was me.

Here's the latest LED thing I'm working on (the design isn't mine): https://immich.home.stavros.io/share/oXerU8gnLn-dNHunPOg8lM8...

Do you know if the panels can be bodged to be non square? There shouldn't be a lot of fancy wiring to screw up if it's all WS2812. Can you (delicately) chop a few LEDs out and bridge the connections?

(hoping I have seeded this idea, so I'm not the first one to attempt this)

Sure, you can connect the LEDs together however you like (am I misunderstanding the question?).

Theoretically you can. It's whether it all goes pear shaped when you take a Dremel to the board to make it

And how fiddly it is to stitch up the edges. I shall find out in a couple of days when the panels arrive.

Oh that's what you mean! Yes, you can, but you'd have to bridge all the data connections by hand. Much easier to just leave those LEDs off in software.
