That’s a fascinating exercise. Picture the amphitheater’s stone still weathered, with the fine ridges of the original masonry visible, but the whole structure overlaid with translucent panels that shift color as holograms flicker across them. The neon arches could sit on top, their bright edges reflecting off the stone, so you keep the tactile feel of the ancient material while letting the digital light play. If you want to emphasize the future, run thin, semi‑transparent circuitry into the walls—think of it as a vein of light running through the stone, so the old and new feel like one continuous thing. That way the texture never loses its age, but the tech gives it a living, pulsing life.
