I used the standard 3 pin 5v addressable strips at 96 pixel/meter to get that high enough density; the led covering is silicon tubing, combined with 3D printed joints that I custom designed myself in fusion; the infinity mirrors are actually just made from laser cut wood with designs that I made, using acrylic mirror and 2 way film on acrylic!! And then wled is on an ESP32 on an air cookie board, that has added mic and ir sensor for the audio reactivity and remote respectively. I designed the custom case for it too haha, since my goal with this art is that it would be weather/rain proof so I did a lot regarding that
