An idea I want to build
A playground without borders.
A family of simple physical interfaces where children in distant cities meet through paint, motion, music, and discovery.
The internet, made physical
Not a screen to watch. Shared Playgrounds turns live connection into something children already understand: a surface to paint, a tunnel to enter, a seesaw to ride, an instrument to play.
Every element aligns bodies, scale, sound, and movement across distance. The technology recedes; another child appears.
Before children share a language, they can share a game.
Two familiar places. One live connection. Play that travels both ways.
Canvas
Paint the same mural.
Children in different cities draw live on one shared digital surface. Every mark travels instantly, so the artwork — and the authorship — belongs to everyone at once.
Gesture → image → collective memory
Tunnels
Crawl toward a new friend.
Two play tubes become one continuous passage. At child height, distance collapses into the simple surprise of meeting someone at the other end.
Movement → presence → encounter
Lookout
Borrow someone else’s horizon.
A climbable tower and remote telescope let children explore the view around a distant playground — then meet the child looking back.
Climb → explore → exchange views
Seesaw
Lift one another up.
Force sensors and responsive motion join two seesaws across distance. A child’s weight in one city becomes movement in another.
Weight → motion → reciprocity
Intercom
Feel footsteps from far away.
Matching floors translate every jump and step into light, vibration, and sound. Children invent games together before they share a language.
Footstep → pulse → wordless game
Sounds
Make one global jam.
Drums, voices, turntables, and chimes synchronize across locations. Each playground becomes one section of a distributed instrument.
Rhythm → synchronization → ensemble
The spatial system
One golden language.
Each piece works alone or as part of a complete connected playground. The family is recognizable across cities, adaptable indoors or outdoors, and built around the scale of a child.
Faces, gestures, and movement remain at human scale.
Every action creates a real response somewhere else.
No lesson or interface is needed. The play explains itself.
A site can begin with one element and grow into the full family.
A new kind of neighborhood
Boston and Beijing. One afternoon outside.
The ambition is simple: children who may never share a street can still grow up with the memory of playing together.
This is an idea, not a product. Nothing here is built yet. If you make playgrounds, build displays, run a museum or a school or a park, or fund work like this — and you want to help make it real — get in touch.
