Over 20k views for this ThreeJS project across Reddit/X/BlueSky/Mastodon in the week I dropped it 🙌🏻

A shame I didn't post it on YouTube right away though, because those numbers really aren't translating into YT views 😅

Day 51. Cluj Globe 🌍

For this project, I explored a scale inversion: Cluj County mapped as if it were an entire planet.

Using OpenStreetMap data, I prepared county-scale textures and wrapped them onto sphere geometry.
Built with Three.js + WebGL, this is not intended as an analytical globe. It is a perspective experiment about how cartographic meaning shifts when context and scale change.

In the decomposition into weight × level + jump, the Twin Prime Conjecture becomes: "The number of prime numbers with a weight of 3 is infinite"
