it’s a simple effect of dropping shadows, and i think this is a great hack!

would there be some way by doing this with one row of leds and a variating pin in the middle? without making much noise?

Since only one is lit at a time you’d only need 2 shift registers, transistors would be optional. It’s not complex, but probably a pain to wire. Is it worth it? That’s another question.

Anyway, that’s a pretty good design.

If you are going to do one 60-LED deck, you may as well do all three for an even more analog effect.

Elegant design. +1

It is sure possible to build a driver to drive 60 LEDs but the circuit will become more complex. The actual problem is the wiring a mounting so many LEDs. (neatly). I did think about it when i started the project, but finally decided to go with the KISS approach. ( Keep It Simple, Stupd!)

great design though.
