Let's build something together.

SolarSystem.city runs on physical cards, mission postcards, and city-specific artwork. If you're an artist, designer, or studio interested in collaborating — on a card, a postcard series, or a city launch — we'd love to hear from you.

Want a city added instead?

Building it yourself at /plan is the fastest way — you know your neighbourhood better than we ever could, and it goes live for review the moment you submit it. Would rather we take a swing at it? Drop us a line below and we'll see what we can do — just know it'll take longer than doing it yourself.
