AI Playground GitHub
Built and refined with AI

Clear prompts.
Readable code.

A small playground of essays, prompt-engineering challenges, and focused front-end experiments — shaped in dialogue with large language models. The goal: to talk to AI with intent, not incantation.

Articles

Long-form writing on how to work with AI systemically — from regulation loops to the sculptor's craft.

Bulk-rename Files in Bash

I want to rename all `.txt` files in a folder so that each one gets a `backup_` prefix.
03 — Working Demos

Examples

Small, self-contained experiments — each one a tiny proof that prompts can yield clean code.

Example

Analog Clock

Smooth animated analog clock with a black frame, classic black hands and a red second hand. Continuous motion via requestAnimationFrame.

Conway's Game of Life

Interactive cellular automaton — emergent complexity from four simple rules. Click to paint cells, or load classic patterns like the Gosper glider gun and watch them evolve.

Rubik's Cube 3D

Fully interactive 3×3 Rubik's Cube rendered with pure CSS 3D transforms — 27 cubelets, smooth face turns, mouse/touch-drag orbit, scramble, and solved-state detection. No WebGL, no libraries.
