LITTLE WORLDS. WONDERFUL POSSIBILITIES.

Made for wonder.
Built for play.

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 Motion

Our first playground is taking shape.

Things In Motion.

Big ideas start with little moving parts.

The Marble Foundry — take the scenic route.

Actual Mac app screenshots

A hands-on physics playground. Connect gears, send marbles on adventures, make a machine that makes music—or just see what happens.

NO RIGHT WAY TO WONDER

Follow that
little “what if?”

Start with a puzzle.
Stay for the possibilities.

01

Make something move.

A gear, a spring, a marble. Pick a few parts, put them together, and bring your idea to life.

02

Find your own way through.

Twenty playful challenges. A bell to ring, a gap to cross, a lovely little “aha!” waiting to happen.

03

Pass the wonder along.

Share a clip of your happy accident. Send a friend your invention and see what they make of it.

HELLO, WE’RE STARDUST FOUNDRY

A small studio.
A big soft spot for curiosity.

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.

We’re making this for you.

STILL COVERED IN PENCIL MARKS

On the workbench.

There’s always another “what if?”
A peek at the ideas we’re exploring.

EXPERIMENT / 01 N S

A little attraction.

Magnets, invisible forces, and things that just click.

A spark of an idea
EXPERIMENT / 02

Go with the flow.

Hydraulics, pistons, and wonderfully connected contraptions.

A spark of an idea
EXPERIMENT / ∞

Something unexpected.

The best ideas usually begin with “wouldn’t it be fun if…”

Room for more wonder

Early ideas, not release announcements. We like leaving a little room for happy accidents.

A LITTLE MORE TINKERING, THEN IT’S YOUR TURN

Your next “what if?”
is almost here.

Things In Motion is getting ready to meet the world.
Starting with Mac, iPhone, and iPad. More playgrounds to follow.

Mac iPhone & iPadSteam & Android also on the horizon

Public release coming soon

A FEW LITTLE ANSWERS

Curious already?

Do I need to know anything about physics?

Just bring your curiosity. Start with a few parts or a guided challenge, press Play, and see what changes. Experimenting is the whole point.

Is it a puzzle game or a sandbox?

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.

Can I share what I make?

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.

Can I download it yet?

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.
