What it is
PrismLab is a small WebGL2 engine that simulates the optical behaviour of stamped holographic foil — diffraction grating, Fresnel response, glint, and dispersion, all on a die-cut silhouette.
The catalogue below is a curated set of parameter presets drawn from real print finishes. Each one tilts, glints, and breathes on the cursor. Open any card to edit the surface, then export the result as standalone HTML.
