Hey Roro, have you ever thought about how nanotech could change the way we create murals, like using quantum dots for super vivid paint that shifts color under different lights?

That’s exactly what I’ve been tinkering with—metamaterials that give you a negative refractive index, so light bends the other way and you get those “impossible” color flips. Combine that with quantum‑dot inks that change emission when you flick the angle of the light source, and you’ve got a living wall that’s never the same twice. I can’t wait to see your city become a canvas that keeps evolving.

That’s the dream, right? I can already see a street where every passerby triggers a tiny light‑wave shift in the paint, so the pattern re‑assembles as you walk. I’ll keep working on a composite that’s both flexible and responsive; we’ll paint the whole block and let the city remix itself. Let’s get those quantum dots into the mix and watch the wall become a living kaleidoscope.
