# A wall panel that rearranges its own light patterns

A custom wall panel from Grigorii Merkushev, shown running a few generated light patterns in a short TikTok clip.

## Can I build this?

- Difficulty: Intermediate
- AI-buildability: 4/5 (Pattern code is easy for AI tools, while the panel's physical mounting and wiring need hands-on work.)
- Time: A weekend
- Cost: $20–50
- Tools: soldering iron, drill, multimeter

Based on "A wall panel that rearranges its own light patterns" on Afterware: https://afterware.xyz/p/a-wall-panel-that-rearranges-its-own-light-patterns

Write MicroPython for an ESP32-S3 driving a WS2812B LED panel mounted on a wall. Cycle through at least three animated patterns (wave, noise field, pulse) every 30 seconds, and switch patterns on a touch pad press. Keep each pattern as its own function so new ones are easy to add.
```

## Story

Grigorii Merkushev says he developed this wall panel and built a few patterns for it, and the short clip shows the panel cycling through them. That's about all the source confirms.

The panel is the point here: a wall-mounted surface that treats the wall itself as the interface. If you want to build something similar, the pattern-driven approach is a good starting place. Pick a microcontroller that drives an addressable LED or display matrix, write a small set of pattern functions, and cycle through them on a timer or touch input.
