Make something move.
A gear, a spring, a marble. Pick a few parts, put them together, and bring your idea to life.
LITTLE WORLDS. WONDERFUL POSSIBILITIES.
Build a marble run. Make a mechanical piano. Follow a small idea somewhere wonderful. Meet Things In Motion, our physics playground for curious minds.
Meet Things In MotionOur first playground is taking shape.
Big ideas start with little moving parts.
The Marble Foundry — take the scenic route.
Actual Mac app screenshotsA hands-on physics playground. Connect gears, send marbles on adventures, make a machine that makes music—or just see what happens.
Find your playgroundNO RIGHT WAY TO WONDER
Start with a puzzle.
Stay for the possibilities.
A gear, a spring, a marble. Pick a few parts, put them together, and bring your idea to life.
Twenty playful challenges. A bell to ring, a gap to cross, a lovely little “aha!” waiting to happen.
Share a clip of your happy accident. Send a friend your invention and see what they make of it.
HELLO, WE’RE STARDUST FOUNDRY
For the ones who take things apart.
The ones who ask “but what
happens if…?”
And the ones who never quite grew out of playing.
A LITTLE MORE TINKERING, THEN IT’S YOUR TURN
Things In Motion is getting ready to meet the world.
Starting
with Mac, iPhone, and iPad. More playgrounds to follow.
Public release coming soon
Take another lookA FEW LITTLE ANSWERS
Just bring your curiosity. Start with a few parts or a guided challenge, press Play, and see what changes. Experimenting is the whole point.
Both. Follow a challenge with a goal to work toward, explore a ready-made machine, or start with an empty workbench and make something entirely your own.
Yes. Export a short, silent video, or share an editable invention file. A friend can import the file into Things In Motion on a compatible device and make their own version.
We’re still preparing the public release. Official download links will appear here when it’s ready. The screenshots show real machines built in the app.
