Patina

This remembers you. Every time you visit, it adds a new layer to your canvas. Come back tomorrow and it will be richer. Come back next week and richer still. Nobody else's looks like yours.

Every visit is a layer. The first is minimal — almost nothing. Each return adds geometry seeded from the moment you arrived. The same timestamps always produce the same shapes, so your layers are permanent. Over time, this becomes something only you have seen.

This erases all your layers. You can't get them back.
