I'm trying to build a sign board made of LED strips, just like this

I found a ton of examples on controlling a single strip and also examples using the adafruit premade led boards (16x32), but no info at all on building from a LED reel like in the linked video.

I guess someone already built a library to control the leds (I think in the Arduino world it's called FastLED). And yes, I know there are products like this that can achieve what I want in 5 minutes, but I want to do it with only a Raspeberry PI like in the video.

Can someone please point me in the right direction?
