At least it was a fun father-son-project. I wrote the server part, he the client part.

First there is the web frontend (sending click requests to a script that saves the clicked pixel in a database, heartbeating to a script to refresh the "image")

You can emulate the rgb output:

Then there is the 64x64 RGB matrix and a raspy connected to it. It is quite hollow on it's back, giving the raspy some place to hide:

backside

The code on the raspy connects to the server and refreshes it's image, if a change happened.

I also "hid" the matrix inside a canvas frame, to help diffusing the single RGBs a bit:

This is, how it looks in the dark:

Sorry for the bad image quality.

That. Is. Awesome! Such a cool project. I have a pie hanging around somewheres, is love to try something like this.

I say: Do it. Those boards come in different sizes, don't cost a fortune AND (here comes the real awesome part) you can connect them to a big array.

Animations also look real cool on it.

If I had an Idea and the right arguments ('ello Wife 👋) I would love to build some sort of text-scrolling array of 3 or 4 those.
