🌌 This time, I decided to invent some planets.
I created The Cabinet of Imaginary Moons, an interactive atlas of worlds that have never existed.
✨ Enter the Cabinet of Imaginary Moons
Inside is a little astronomical observatory. Every time you press Another moon, the telescope discovers a new world, complete with a name, geography, atmosphere, and a short field report.
You can explore six types of worlds, including frozen moons, volcanic landscapes, ocean planets, and enormous gas giants.
But you can also become the cartographer. Change the sea level to drown continents, turn the sunlight to reveal the night, introduce clouds, or surround your planet with rings.
My favorite feature is the world passport. Every world has a reproducible code. You can copy it, experiment with other planets, and return to exactly the same world later. You can also save an illustrated postcard from your expedition.
Underneath the fiction, the geography is generated using multiscale noise, mapped onto a sphere, and illuminated using geometric calculations.
I tested the interactive controls, passport restoration, and postcard export in a browser, including a mobile-sized layout.
The atlas works entirely offline.
I particularly wanted to create something in which exploration and creation are the same activity: you discover a world, but it exists only because you decided to look for it. 🌿
