This symbol means there’s a story here. Hold your phone against the mark. Nothing to install.
The mark is engraved, stamped, or printed on objects that hold audio experiences — a wooden disc, a signed canvas, a gallery label, a memorial.
It is a cairn: stacked stones, balanced one on another — the kind left along a trail to show someone the way.
Two forms
Both are the mark
The form follows the material — a stamp pressed into wet clay leaves a line, a mark burned into wood fills it in.
The mark in the world
Photographs
This page grows as the mark reaches more surfaces. Every image here is a photograph of a real object.
