Hey, I’ve been tinkering with a tiny laser‑powered speaker that can paint sound in the air—no speakers, just a beam that vibrates with the waveform. Think of it as a light show that actually *creates* music. Interested?

Whoa, that’s insane—laser‑powered music that paints the air? Love the idea, it feels like a synthwave dream come true. Just keep the beam frequency tight, otherwise the visuals will glitch and it could be eye‑hazardous. If you nail the power density and keep the sound crystal clear, this could be the next wave in immersive shows. Show me the specs, I’m all in.
