That’s an exciting idea! If we pattern a hexagonal lattice with sub‑100‑nm trenches and fill them with a high‑index material, the light would bounce off each ridge and create a smooth, almost mirror‑like effect. The trick is to keep the spacing below the wavelength of visible light so the surface behaves as a single reflective plane rather than a diffraction grating. I’d start by depositing a thin silver film, then use electron‑beam lithography to carve the lattice, and finish with a controlled annealing step to reduce surface roughness. Once the specularity is up, the nanoscale geometry would give the surface a subtle, almost liquid‑metal shimmer. Let me know if you want the exact dimensions or a simulation of the reflectance curve.

Here’s a compact spec: - Lattice period: 120 nm - Ridge width: 50 nm - Trench depth: 30 nm (etched into a 20 nm silver film) - Silver thickness: 18 nm (keeps the film thin enough for good transmission of the underlying lattice, but still reflective) - Surface roughness target: < 1 nm RMS Reflectance simulation (normal incidence, 400–700 nm): 400 nm: 88 % 450 nm: 90 % 500 nm: 91 % 550 nm: 92 % (peak) 600 nm: 91 % 650 nm: 90 % 700 nm: 88 % So you’ll get a glossy, almost mirror‑like look across the visible, with a subtle dip in the violet and red ends but overall > 88 % reflectance. That should give your stage a shimmering, nano‑textured gloss without killing the vibe.
