Signal Hunts
Short, repeatable exercises where students try to pull real signal from noisy data: clickstreams, A/B tests, or simulated lab results.
Built to run in 5–20 minutes, with exports you can reuse in later lessons.
Ghost Citadel · Scriptorium
Interactive lessons built like games, not slide decks.
We turn one lesson you already teach into a short, replayable experiment — something students can touch, break and rebuild while you stay in control.

What We Build
Scriptorium is our classroom lab inside Ghost Citadel. We prototype small, focused tools that plug into the lessons you already run — with analytics ready from day one.
Decision Engines
Scenario-based games where students act as leaders or operators, make choices under pressure, and see the consequences unfold.
The Estonian independence prototype below is one of these engines.
Job Simulations
Lightweight “day in the life” terminals, built for internships, bootcamps and early-career hiring. No trick questions — just real tasks.
Ghost Terminal, our assessment demo, is the first public example.
Why This Exists
Slides Can’t Carry It All
Traditional decks are great for structure, not for experimentation. Students watch, answer a few questions, and move on — but the real learning happens where they can try, fail and adjust.
You Don’t Need Another Platform
We build small, self-contained experiences that run on top of your existing systems. No new logins, no LMS migrations, no heavy rollout.
Data That Feels Like a Story
Every run can export clean telemetry: who tried what, where they struggled, and which paths surprised everyone. Perfect for reflection, grading rubrics or follow-up projects.
Scriptorium Lab — Playable Prototypes
The projects below are working sketches, not final products — exactly what we would bring into a workshop with your team before we build something custom.
Ghost Terminal — Job Simulation
A technical assessment that mixes puzzles, code snippets and system-design questions. It runs inside a retro terminal, but the scoring logic is modern: timing, accuracy and how fast you recover from mistakes.

TECHNICAL ASSESSMENT
Estonia 91 — The Swipe of History
A classroom-ready prototype about the Singing Revolution. Students swipe left / right through key events and watch how unity and risk shift with each decision.
UNITY: 50%
KGB: 10%
Start With a Signal Hunt
The easiest way to try Scriptorium is with one narrow lesson: a single dataset, a single concept you want students to master, and 20–40 minutes of classroom time.
Talk About a Signal HuntWe’ll come back with one or two concrete prototype ideas — including how telemetry and the Observatory layer can support your teaching without adding extra admin work.
