Love it! I did a similar thing, 64x64 pixels with a LED diffuser. Everything is packed up in the IKEA picture frame: https://imgur.com/a/cLXGWWd

I'm lazy, but I plan to do the full write up and to open source everything. I use it to display pixel art, and during the night it automatically switches to the clock mode.

I love yours as well and it would be great if you can put the code on GitHub. Mine is using ESP32 as well (Adafruit's MatrixPortal M4). It is running Circuit Python though. I love it dearly and I played with an idea of making it as a product.

As promised, here is the repo: https://github.com/hanneslinder/esp-pixel-matrix

Using a pictureframe is a cool idea! I actually have an 64x64 matrix in my drawer that I havent used yet. Should you decide to open source your code I'd be very interested too.

I'll update my comment tomorrow with a GitHub link, just need to tidy up the repo first. This was my very first time writing c++, so the code is probably not the cleanest ;)

Same story with me and python, so don't worry :) I'll make the repo public during the next week.

Diffuser also makes a difference as the controller I'm using doesn't allow me to control the brightness. I should really write a blog post :D
