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.
- One card, every city, forever. It carries no city and no planet — which one you see is worked out from where you're standing.
