RunTheSimabout
A library of playable simulations.
One at a time.
RunTheSim is a library of browser simulations for curious adults who like seeing a thing emerge — and then nudging the parameter that made it possible. Free today. Login tier later. Paid tier when it earns its place.
what this is
Three things at once
Every simulation in this library serves three roles simultaneously. If it can't do all three, it doesn't ship.
who
Who this is for
Primary audience is curious adults 25–45 internationally. Students and self-learners are secondary. Teachers and educators are amplifiers, not customers.
Curious adults
You got hooked on Kurzgesagt, Veritasium, 3Blue1Brown, Quanta, Nicky Case. You understand enough maths and code to enjoy emergent systems — but you don't necessarily build them yourself. You have disposable curiosity.
The simulation hooks you on Instagram in 90 seconds. The site is where you come when you want to steer the thing yourself.
Students and self-learners
High-school and early-university age, finding content on your own. You weren't assigned this. You came because it looked smart enough to share.
Teachers and creators
If a teacher shares RunTheSim in a class, that's 30 students reached. If a creator does a reaction video, it's tens of thousands. You're distribution leverage — not the design target.
why
Why this exists
Wonder earns the hook.
Tinkerer gets the handoff.
Passive content dies. Pure tools don't travel. The specific move RunTheSim makes is: the video hooks with wonder, then the site hands over the controls. The sim is both the argument and the proof.
Exploration over prescription.
We don't teach. We show how to think, hand over the parameters, and trust the reader. The simulation is the lecture. The text is a guide, not a syllabus.
Recordable-first.
Not perfect-first.
A simulation ships when it can be recorded as 60 seconds of video and point to a working URL. Ten shipped simulations beat one perfect one. Polish is the thing you do after the loop is closed.
