A multicolored IFS fractal flame — magenta, teal, and gold filaments swirling on black — rendered in Lumen Apeiron

Paint with
infinite chaos.

Lumen Apeiron (formerly Chaos Master) is a GPU-accelerated IFS flame fractal generator for artists and explorers — millions of iterations rendered live, shaped by your hand. No install, no render queue.

Move your cursor over the flame. Requires a WebGPU browser — Chrome / Edge 113+, Safari 17+.

Built for hands-on exploration

A studio that keeps up
with your imagination.

Everything renders live in the browser on modern web standards — no native app, no plugins, no waiting.

01

WebGPU rendering

Real-time IFS evaluation on the GPU — millions of iterations a second, redrawn the instant you touch the flame.

02

Animation

Keyframe any parameter and play it back. Morphs, seamless loops and timeline scrubbing — your flame in motion.

03

Randomizer

Roll a brand-new flame, then mutate it — shapes, colors and animation — until something surprises you.

04

3D flames

Sculpt fractal flames in three dimensions, with an orientation gizmo and a full set of 3D variations.

05

Affine & variations editor

Grab transforms directly on the canvas, and write your own variations in WGSL or plain math.

06

Metadata-rich exports

Export PNGs with the full flame state embedded — any image reopens and remixes. Sharing is just a file.

07

Audio flames

Make the flame dance to music. Wire beats, bass and spectrum to any parameter with a node-graph editor, then export the performance to video.

08

Flame genetics

Breed two flames into offspring, evolve them across generations, or let the population simulator run — every lineage kept in an ancestry tree.

09

Sonification

Hear the fractal. The flame structure itself generates real-time audio, turning geometry into an instrument.

Under the hood

The math, live.

Define affine transforms and variations, weight their probabilities, and let the GPU resolve millions of iterations in real time. Drag the coefficients — the flame re-solves under your hands.

Explorers welcome
