Open the work. Poke at it. Learn something.

Turn a cube, trace an algorithm, or explore a recorded world. Pick a learning lab and start without signing up. Find the rest of my work in Projects.

Learning labs

Learn by doing

Small, focused experiences that make an abstract idea tangible enough to touch, predict, and explain.

    Algorithms · interactive course

    SortLab

    Trace 18 sorting algorithms one decision at a time, predict the next operation, and compare what their complexity claims look like on real input shapes.

    • Explanations for every comparison, write, and swap
    • Guided predictions and contextual practice
    • Side-by-side empirical operation counts
    • 18 algorithms
    • step-by-step

    Ages 2+ · grown-up co-play

    Baby's First AI

    Five short, talking, fail-free games that turn classification, training, clustering, prediction, and listening into things a young child can play with.

    • Child-only public edition with no camera, microphone, or API keys
    • TV remote, keyboard, touch, and reduced-motion support
    • Each session ends with an off-screen real-world activity

    Rubik's Cube · four methods

    Twist

    Learn to solve a 3×3 on a cube you can actually turn: the beginner method first, then CFOP, Roux, or ZZ, with a trainer that drills the cases you keep missing.

    • Every algorithm demonstrated on a cube you can rotate and replay
    • Recognition and execution drills weighted toward your weak cases
    • Sandbox timer with +2/DNF, a daily drill quota, and colorblind mode
    • live 3D cube
    • 276 algorithms
    • timed trainer

Worlds & workspaces

Inspect what the system did

Explore recorded worlds and the evidence behind larger projects. Replay editions let you inspect what happened without running a live simulation.

    Curated archive · evidence first

    Generative World Museum

    Read the long-running Hollowbrook chronicle and open the Glass Box on a second agent world, with sources, limits, and system evidence kept beside the stories.

    • Curated events from persistent autonomous worlds
    • Inspectable memories, cognition, and relationship changes
    • Replay-only publication boundary with no live model
    • replay archive
    • agent memory
    • relationships

    3D replay · autonomous agents

    AI World Replay

    Walk around a recorded autonomous village, follow its agents, change the camera, inspect what they were doing, and control the replay without running a local LLM.

    • Bundled, deterministic world recording
    • No backend, WebSocket, mutation, or visitor prompt input
    • Multiple camera modes and adjustable replay speed
    • Three.js
    • recorded world
    • camera controls

    Public workspace · searchable evidence

    Tesla Builder Lab

    Explore the applications, dependency graph, reproducible demos, research clusters, and decisions behind the Tesla OSS workspace from one public-safe command center.

    • Filterable project and evidence catalog
    • Registered demo fixtures with honest lifecycle labels
    • Hundreds of searchable, grouped product ideas
    • OSS catalog
    • architecture
    • research explorer

Outdoor tools

Take it outside

Tools for time away from the desk. Take GolfRay onto the course for GPS yardages, club advice, and offline access.

  • separate site

    On-course caddie · live GPS

    GolfRay

    A phone-first caddie you actually walk the course with: GPS front/centre/back yardages, what the shot plays like in the wind and slope, and the club for your game rather than a tour average.

    • Distances adjusted for wind, temperature, and elevation change
    • Club advice learned from your own logged carries, shown as a P25–P75 range
    • Ohio courses imported from OpenStreetMap with real green outlines and approximate hazard markers
    • installable PWA
    • works offline
    • real course data
    Open on your phone

    Opens at golfray.raymondriter.dev. Allow location access there to get GPS distances on the course.
