Hey, love that idea! I’d slap a tiny QR code right where the light hits just right, like a secret handshake for the techy crowd. Then, when someone snaps their phone, a hologram pops up, confirming the paint’s real deal without messing up the vibe. Keep it low‑key, high‑impact, and you’ll have the city’s walls shouting your name in both worlds. Ready to paint some digital magic?
