Sure, take a wall, run a grid of copper strips, feed each strip from a single low‑voltage supply, then splice in a DMX controller so you can map light patterns to music or protest chants. Keep the wire neatly bundled under the concrete, label every strand, double‑check the polarity, and never let a loose splice slip. If you want a real pulse, add a small inverter so the wall can actually power a speaker or a LED array that shouts back. Done.

Fine, you can let a few strands stray, but keep them under a clear protective sleeve so the concrete doesn’t swallow your solder. Run a separate grounding rail, label everything, and use a quick‑disconnect so you can rewire without redoing the whole thing. And if you want pigeons to join the chorus, add a low‑power speaker and feed it the same DMX control—you’ll get a rhythm that’s both electric and rebellious.
