I have a piece of very thin flexible material that has multiple copies of a test message, but when engraved at different depths it shows different colors. My thought is that it’s ideal for making bookmarks. It wound up in our Glowforge project sample drawer when my predecessor left, and I’ve got no idea what it is or where she got it.
