RunTheSimabout
A library of playable simulations.
One at a time.
A collection of browser simulations that let you watch how a shape falls out of a rule. Press play, change a parameter, ask why. That's the whole site.
what this is
Same simulation, three places
Every simulation lives on three surfaces at the same time. The web version is the full thing, the video is the preview, the email makes sure you do not miss the next one.
who
Who this is for
Curious people who like to poke at things and see what happens. Age and background do not matter much; the interest does.
primary
Curious adults
You follow science channels for the hook. What you have been missing is the slider. Every simulation here puts you in control of the rule that produced the shape you usually only get to watch.
The short video meets you where you already scroll. The site is where you land when you want to steer the thing yourself.
secondary
Students and self-learners
Nobody assigned this. You opened a simulation because it looked interesting and stayed because it kept being interesting. No login, no paywall, no quiz. Learn at the speed that feels right, or just play.
amplifier
Teachers and creators
Every simulation runs in a browser with no account. Embed one in a lecture, link it from a syllabus, screen-record it for a reel. A credit to RunTheSim is appreciated, not enforced.
For anything that needs offline use, a classroom bundle, or an embed feed that pulls live updates, write to hello@runthesim.app and we'll figure out what fits.
why
Why simulations, not videos
steering
Watching is passive.
Steering is not.
A video shows you the shape once. A simulation lets you change the rule and watch the shape sharpen or fall apart. The gap between those two is the gap between knowing about a thing and actually understanding it.
rules
Simple rules, big shapes
Everything here runs on a small number of local rules. The interesting part is that nobody programmed the shape: the shape appeared. Once you see that pattern, you start seeing it everywhere.
time
Short on purpose
The sixty-second video on your feed and the playable version on the site point at the same insight. Neither asks for more of your time than the insight is worth.
