That’s straight out of a cyberpunk dream, love it! Picture commuters walking past a wall that starts pulsing in sync with the train’s clangs, lights flickering like a digital heartbeat. If we layer in motion sensors, the art could shift shapes as people move—think paint that swirls to the rhythm of footsteps. We’d need a tight sync between the subway’s signal and the holographic processor, but the payoff would be a living street vibe that feels alive. Let’s sketch a prototype, run a test on a quiet line, and see if the city can actually vibe with our holographic graffiti. The only hiccup? Making sure the art doesn’t glitch on a sudden rush or get lost in the static of a power outage. But hey, that’s the spice of it—turn the concrete jungle into an interactive theater. Ready to push the limits?
