I built a game on my old phone without knowing what I was building
I'm calling this "Vibe Discovery" — distinct from vibe coding because I didn't know the requirements upfront. Started with "make something with the accelerometer" and discovered through 6 iterations that I wanted a WebGL marble game. The interesting part was the dev setup: Claude Code running in Termux on a Redmi Note 9 (4GB RAM). The same-device feedback loop — code, test accelerometer, react, iterate — made rapid discovery possible in a way that laptop-to-phone deployment wouldn't.
In plain words
A WebGL marble game developed iteratively on a Redmi Note 9 using Claude Code running in Termux. The maker discovered the final concept through six iterations starting from an open-ended accelerometer challenge. The development approach emphasizes same-device feedback loops, where coding, testing with the phone's accelerometer, and iterating happen on the same device, enabling rapid discovery and refinement that traditional laptop-to-phone deployment workflows would not support.

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…
- VCVibe Coding a static site on a $25 Walmart PhoneJan 2026 · stetsonblake.com · ▲76
Hi! I took a cheap $25 walmart phone and put a static server on it? Why? Just for a fun weekend project. I used Claude Code for most of the setup. I had a blast. It's running termux, andronix, nginx, cloudflared and even a prometheus node exporter. Here's the site: https://walmartphone.stetsonblake.com/

Like a lot of people I got the $250 Claude Code credit and didn't use it up. I decided to try to use it up over the weekend using (mostly) my phone and vibe coded a Prolog interpreter. Now I'm seeing how far I can push it.

We built this on a whim for a hackathon, but I'm thinking to turn it into a real thing! Original GitHub repository at: https://github.com/Flux159/claude-code-go The desktop app exposes an interface to Claude Code, so you can run Claude Code from your phone.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
