👋 Hi, I'm Serhii — aka xcont
I'm a self-taught developer working at the intersection of optimization, pattern formation, and cellular automata.
I build experimental systems where complexity emerges from simple rules — using code, recursion, and a bit of imagination.
🧬 Core Projects
🔷 The Billiard Fractals
Exploring fractals generated from symbolic billiards, irrational discretization, and curved surface slicing. A bridge between number theory and emergent geometry.
→ billiard-fractals
→ full article
🔁 Evolving Cellular Automata — Rule-Based Evolution
Genetic algorithm that evolves cellular automaton rules to maximize specific behavior (like flickering, stability, or growth).
→ evolving-cellular-automata
→ full article
🧠 Evolving Initial States — Field-Based Optimization
A genetic algorithm evolves the initial field state of a cellular automaton while keeping the rules fixed.
The goal: observe what kinds of behavior or structures can emerge from a Turing-complete substrate.
It’s a search for dynamics, complexity, or stability — without touching the rules themselves.
→ initial-state-evolution
🧩 Recursive Fractal Generator + GA
Fractal patterns generated via recursive substitution, then evolved using a genetic algorithm.
Focus: visual symmetry, self-similarity, and how simple logic creates structured complexity.

🌀 Fractogenesis: CA vs Conv
Fractals from a single point — grown using either cellular automata or convolution kernels.
This project explores 6 minimal systems that all follow the same basic idea:
Start with a tiny seed, apply a deterministic transformation, pad or copy, repeat. Fractals emerge.
But here’s the twist — CNNs (convolutional neural nets) do the same. They copy, convolve, repeat.
So what happens when we apply the same kernel over each iteration? You get... fractals.
Turns out, when a neural net "draws a cat", it draws a fractal that looks like a cat.
→ fractogenesis
🧮 Perfect Shuffle Fractals — Recursive Spatial Permutation
Fractals generated by recursively permuting pixel arrays via a quadrant-based shuffle operation.
This deterministic process reveals deep structural symmetries in both binary and full-color images.
The method echoes spatial structure-modification routines found in convolutional architectures (e.g., padding and upsampling),
though it diverges from convolution by applying no local aggregation — only recursive, deterministic reordering.

🎼 Perfect Shuffle Music Composer
A generative MIDI tool that evolves musical patterns using deterministic shuffling and genetic algorithms. Built with Node.js + MIDI export.
→ perfect-shuffle-music
🤖 NeuroParticles — Artificial Life with Evolving Agents
Artificial life on a grid: each particle is controlled by a neural network.
They move, sense, and fight — evolving through a genetic algorithm.
The goal isn’t predefined — just survival, competition, and strange emergent behaviors.
→ neuroparticles
🛡️ Perfect Shuffle Cryptography — Deterministic File Encryption
A minimalist encryption scheme based on recursive, invertible spatial shuffling.
Pure, deterministic logic with visual twist.
→ perfect-shuffle-cryptography
🌌 Particle Simulation — Coulomb Forces in a Toroidal World
Interactive 2D particle system with electric-like forces and edge wrapping.
Built in JavaScript with live controls for mass, charge, and interaction strength.
→ particles
🌱 T-Fractal Builder — Recursive Overlay at Multiple Scales
Tiny sandbox to create layered fractals by scaling and overlaying a simple pattern.
Playful and deterministic — showing how recursion builds structure from almost nothing.
→ t-fractal

Complexity isn't magic — it's just logic repeated until it surprises you.
