What it does
- It sets the scale. Point your phone at the card and the app knows exactly how big it is — that's what lets it draw a planet at true size on the pavement in front of you.
- No app to install. Scan the code, and the walk opens in your browser.
- The back is an AR target too. If you'd rather not carry the wallet card, hold up the postcard instead — it's tracked at its own true size.
The walks it covers
About this card
The founders edition is one print run that covers every walk we publish. The artwork is the same on each; what differs is the QR code, which is printed for your walk when the order is packed and applied over the panel at the lower right.
The back is an AR target in its own right, tracked at its true 7-inch width — so if you'd rather not carry the wallet card, you can hold the postcard up at a planet instead.
Every piece of artwork we sell is commissioned from a person and paid for. Read our policy on generative AI, or work with us.
