What makes a wall
stay up?
A rectangle can lean. A triangle holds its shape. Sometimes one small change makes all the difference.
Give this frame a push. Then add a diagonal and see what changes.

For curious kids. And their grown-ups.
More “I wonder.”
More “I made that.”
Make room for the questions, experiments, and small discoveries that turn into real understanding.
- A simple, private start
No child account. Learning progress stays on this device.
- Room to find their own pace
Pause, revisit an idea, and try again. There’s no race to finish.
- Better with a grown-up nearby
You guide the learning and supervise activities away from the screen.
Grown-up’s guide
Settle in together.
Ages 10–14. A browser, a little curiosity, and 40–60 minutes are enough to begin. No tools or materials are required for the on-screen missions.
Let the model explain.
Play Atlas and follow the highlighted boards, or read along at your own pace. Each mission moves from an explanation through a build, calculations, and a design to test. The lesson’s Q&A and Field card are always nearby.
Be there for the real world.
Open Adult guide inside a lesson for its specific notes. Supervise Serve activities with a qualified adult. Stay outside work areas and keep tools, live electrical systems, plumbing, and fire equipment out of the activity. This is an educational simulation, not permission or instructions to build a real structure.
Keep the learning here.
Progress stays in this browser on this device. Print a Field card for a paper record. Children never sign in; an adult account manages household access and billing.

Before you
begin.
A few things you might be wondering.
What devices does it run on?
A modern browser with WebGL. Nothing to install. If 3D acceleration is missing, the lesson, numbers lab, assessments, diagrams, and Field Card stay available as text.
Does it work offline?
Once the Academy file has loaded, fonts and the engine are embedded in that file, so the lesson keeps running with the network off. Progress is stored only in that browser.
What ages is it for?
Every lesson is marked Ages 10–14. The learner is the child. The account, if you create one, belongs to the adult.
What does an adult do?
Own the account and any purchase, open the Adult Guide from the lesson menu, supervise Serve missions (they begin “With a qualified adult”), and print Field Cards if you want a paper record. See the mission brief for the full list.
Does my child need an account?
No. Lessons 01–05 need no sign-in. Children never sign in. Progress and Honor stay in the browser on the device where the lesson is played.
What do you store?
If you create an adult account: your email and password with Supabase, your entitlement, and a Stripe customer id if you pay. Nothing about the child. Academy progress is not uploaded.
Can two children share it?
Yes. One household plan. Progress is per browser, so two children on two devices each keep their own Honor.
How do refunds work?
Support and refund handling is being set up before checkout opens.
