Renura's living Android home screen drawn entirely in code
Claude (Fable) built a home screen for a mindful-scrolling app that changes with the time of day and moves on its own, with no images or video.

The full story
Renura is a free Android app that notices when scrolling has become automatic and offers a gentle moment to pause. Its home screen is meant to feel like a small living world: the atmosphere changes with the time of day, water ripples, and a glowing orb breathes and responds to touch.
The developer used Claude (Fable) to build it over many iterations. None of it is an image, video or pre-rendered animation; it is all generated in code. One change that made it feel right was keeping the orb still and moving the breathing inside it, rather than letting the whole orb drift.
The whole app is under 12 MB, and its behavioural processing runs on the phone without reading screen content.
