Built with QuorX
Demos you can try live.
Two apps from real QuorX 0.2.12 runs. Each started as one request; QuorX planned it, wrote it, tested it, checked it in a real browser and had it reviewed. They're hosted here as they came out, with the run that made them.
Live weather, air and a kite game
Skyline
Live weather and air quality for any city, a sky drawn from the real conditions, and Kite Day: fly a kite in the city's real wind, the next 24 hours of forecast squeezed into 60 seconds.
The request asked QuorX to research a free weather API in the browser first. It worked in its own Chrome tab group: read the Open-Meteo docs, watched the page's network requests to find the API, read the responses, then built Skyline and played its own game.

The live demo asks Open-Meteo for weather once you open it; Open-Meteo sees your IP address and the cities you look up. Weather data by Open-Meteo.com, CC BY 4.0.
Gravitational lensing, in your browser
Black Hole Lab
A black hole you can play with: gravitational lensing ray-marched on your graphics card, a Doppler-beamed accretion disk, and probes you fling onto relativistic orbits that precess into rosettes.
QuorX wrote the physics and the renderer with no libraries, tested the physics, opened the lab in a real browser and had it reviewed. The video is the 26-minute run as a timelapse.

The live demo is a heavy real-time simulation. It checks your graphics acceleration first and starts only when you press Start.
