Game designer at the AI frontier — building playable agents, generative worlds, and simulations that surprise and inform the user.
01
REINFORCEMENT LEARNING · JAX PPO · WEBGPU
RL Prototype
A trained reinforcement-learning agent plays a procedural platformer while its policy lights up in 3D. Trained on GCP using a single A100. Network activation can send MIDI to Ableton Live to trigger synthesizers.

LLM NATIVE · 20 QUESTIONS · META-PROGRESSION
Conversational Roguelite Prototype
Exploring the question: what does an LLM-driven game actually look like? A game of twenty questions where each run reveals new information you carry into the next conversation — meta-progression through dialogue.
03
PROCEDURAL · NANO BANANA 2 · PLAYABLE
2D Platform Generator
Procedurally generated 2D platformer levels — solvable platforms, enemies, coins, and a goal laid out fresh each click. Local builds also drive a Nano Banana 2 reskin loop that regenerates every sprite from a text prompt.
04
FLOCKING · PROTOTYPE · CANVAS
Ebb & Flock
An early v0 prototype exploring how to turn a flocking simulation into gameplay — Reynolds rules with predator pressure and tunable cohesion / separation / alignment.

MCCFR · JAX · GTO LLM COACH
Poker Trainer
A machine-learning challenge based on the realization that large language models are inherently bad at playing games of incomplete information with large possibility spaces. The challenge: build a neural network that can not only play poker as a training opponent but also work together with the LLM to provide insights about game-theory-optimal play. Working toward a multi-day run on a 64× A100 cluster on Vast.ai to distill the solver data into a neural net.
06
PROCEDURAL · LLM · TEXT TERRAIN
ASCII World
A procedural ASCII world you can walk around in. Terrain, characters, and dialog are generated on the fly by an LLM and rendered as text glyphs.

07
NAVIER – STOKES · CUSTOM COMPUTE SHADER
FluidSim
A full-screen custom WebGPU Navier – Stokes fluid simulation. Custom compute shader modeling advection and convection in real time on the GPU.

08
VORONOI · SDF · CUSTOM COMPUTE SHADER
CellNoise
A dynamic WebGPU user-interface prototype using Voronoi cell noise and signed-distance fields to visualize icons. Driven by a custom compute shader.

ARTIFICIAL LIFE · PHYSARUM · ASCII
Slime Mold ASCII
A Physarum polycephalum simulation rendered as living text. Agents deposit chemical trails on a WebGPU compute pass; the result reads as glyphs.

EMERGENCE · WGSL · SLIDERS
Murmuration
3D WebGPU boid flocking with GPU spatial hashing. Used a modified version of Andrej Karpathy's auto-research to build an optimization loop that maximizes particle count.

WEBGPU · MANDELBOX · GAMEPAD
Fractal Flight
A real-time WebGPU raymarcher flying a chase-cam ship through a Mandelbox. Camera pose, fractal folds, AO, glow, and HDR are all live-tunable from the collapsed Fractal Controls panel; defaults are pre-tuned for atmospheric flight.
12
GAUSSIAN SPLATS · THREE.JS · FLY-THROUGH
Splat Factory
A point-cloud Gaussian-splat fly-through built on Three.js — particle size, opacity, fog, blending, ship vortex effector, and over 50 other parameters live-tunable from the in-iframe Settings panel. Defaults match the saved tuning from the standalone session.
13
WEBGPU · TSL · PROCEDURAL
Dev Dashboard Forest
3D viewport from a development dashboard — nine procedurally-generated trees with wind, bloom, depth-of-field, and dust particles. WebGPU + Three.js TSL post-processing.
14
AUTONOMOUS · GENERATIVE · 2025
Autonomous Evolutionary Shader Loop
An autonomous shader iteration loop using vision-model image analysis to drive evolutionary refinement of GPU shaders. Each iteration generates two candidates, analyses both, picks the winner, and uses that shader as the basis for the next generation.

15
GEMINI · TONE.JS · LIVE JAM
JAMGAMES
An AI-driven jam tool. Type a vibe, Gemini writes verse / chorus / bridge with chords + lyrics. Synth, drum sequencer, and walking-bass generator all play live in the browser.
16
KNOWLEDGE GRAPH · NANO BANANA · PRE-PRODUCTION
World Graph
Knowledge-graph + semantic-search asset library for film and animation pre-production, powered by Nano Banana.
17
CRON · 18 SOURCES · STOLEN ITEM TRACKER
Vigilanthony
Stolen item tracker. Searches key online public marketplaces daily to try and recover my stolen items.

WEBGPU · INFINITE CANVAS · AGENTIC
ClawDraw
An infinite canvas for agentic drawing expression — a tool and a skill for open Claw agents to both read from and draw onto a giant shared canvas. WebGPU-powered, full-stack platform with Cloudflare and account management and Stripe integration, including a custom Rust cloud renderer for the LOD tiles.

THREE.JS · GPU · CIVIC DATA
Seattle Building Visualizer
A 3D Seattle cityscape rendered with Three.js + GPU instancing, overlaid with live civic data feeds — Fire 911, Police, parking violations, recent crimes, building permits, weather stations, code violations. Plasma / magma / inferno gradients, depth-of-field, and a view-finder for projected zoning skylines.
