A UK startup called MiniatureMoments has created a fairly unique keepsake for you and yours. These things are 3D-printed negatives that appear when you hold them up to the light. They are translucent and are about as big as a passport photo and custom-designed with your own portrait.
The miniatures, especially their size and color, are actually redolent of an earlier era. I could imagine these being made out of elephant ivory or bakelite in Industrial England, giving them a sort of memento mori, steampunk quality that I find appealing. They’re obviously pretty small but you could probably stick it up in a window or hang it around your neck like some mad-eyed Miss Havisham reliving your dewy youth.
Each miniature costs $40, shipped, which is steep for a rigid postage stamp. Your call.
