# Paper-craft fractal browser

> An interactive fractal browser (Mandelbrot and others) styled like handcrafted paper and cardboard, with cinematic post-processing and animated transitions. Claude Opus 5.5 built it as a Claude artifact; the creator posted a demo video.

## Before you start

Guidance from Reference, separate from the creator's instructions.

1. Read the reference and inspect the project, installed libraries, and available agent skills before writing code. Reuse suitable tools already present.
2. Prefer the creator-reported libraries and skills when they fit the task. Explain what useful additions help with, and install missing project dependencies or relevant skills from official sources when the environment and the user's existing permissions allow it. Respect the project's package manager and setup rules; do not ask again for routine setup already authorized.
3. Distinguish tools used by the creator from your own recommendations. A listed tool is not automatically required, and an empty tools or requirements list means the setup is unknown, not that nothing is needed.
4. Ask concise questions when missing inputs or choices materially affect the result: paid services, credentials, the user's assets, or a different production approach. Use existing answers and permissions; continue independent work while waiting.
5. If a useful library, skill, or service cannot be installed or used, explain an available alternative and its expected effect on quality, features, or effort. Get the user's choice before a material compromise; otherwise state the fallback and continue. Never silently simplify the result or claim to have used a tool you did not use.

## Recreating this website

These are the creator's published instructions, unedited.

To adapt it: Change "a fractal visulizer (mandelbrot, etc)" to another kind of visualizer, and "handcrafted with paper, cardboard and such" to another material.

## Prompt

```text
build an art project which is a fractal visulizer (mandelbrot, etc), but the styles look like handcrafted with paper, cardboard and such. Add post-procesing so it looks cinematic. Also want to use beautitful elaborated animations and transitions and a beautiful UX. Plan it first, show me a preview before coding everything
```

## What it looks like

Written by Reference from the video frames, not by the creator.

A fractal browser drawn as layered cut paper and cardboard: each colour band is a sheet with soft shadows, moving through Mandelbrot, Julia and Newton fractals at deep zoom.

- Color: Kraft and corrugated cardboard browns, cream and white paper, orange and marigold sheets, deep maroon, and one navy Mandelbrot set.
- Type: A rounded multicoloured Paper Fractal wordmark, handwritten-style captions on small white paper labels, and a pink depth and sheet counter in the top right.
- Framing: Full-bleed 16:9 frames of the fractal with stacked paper edges for depth; captions sit lower left and the counter upper right.
- Structure: Title over a cream and maroon spiral, a Mandelbrot bulb in orange paper, gold filigree spirals, a torn reveal from white to orange, Julia sets on white contour sheets, a navy Julia set, Newton's three basins on cardboard 775 million times deeper, and a closing title card reading WebGL2, no libraries, deep zoom by perturbation.

## How it was made, per the creator

- Notes: The prompt asks Claude to plan first and show a preview before coding, so there were later turns that weren't published. The creator calls the prompt very raw, just playing with the concept.
