Freeze
Nobody moves. Not a finger. You move again when I say so. Not one second earlier.
What the square seesHundreds of people stop mid-step, all at once, and stay frozen for fifteen seconds. Then, on one word, they walk on as if nothing happened.
One voice. Hundreds of people. The same second.
SYNC is a shared audio experience on a city square. Headphones on, phone in your pocket, and one narrator guides everyone at exactly the same moment.
A voice in every ear. In sync to the millisecond.
01
Everyone opens the SYNC app and puts on headphones. Then the phone goes in the pocket, screen down.
02
Arthur, the narrator, talks the whole group through fifteen minutes of small, simple and slightly absurd instructions.
03
The square fills with a pattern nobody planned alone. And everyone without headphones wonders what they missed.
The first four minutes.
The funniest part is for the people who are not playing. They hear nothing, and see a square full of strangers doing the same thing at once.
See who is playing
Did you see who froze with you? Those are your fellow players. Now you know who's in.
What players getThe freeze is the first reveal. Everyone who stopped at the same second is in on it, so strangers start to recognise each other.
Sit down
Now, something nobody on this square expects. Sit down. Right where you are.
What the square seesA crowd sitting on the ground, on steps and on fountain edges, for half a minute. Then, all together, they stand up again.
Look up
Now, all together. Look up. At nothing in particular. Just the sky.
What the square seesHundreds of people staring at an empty sky. Within seconds, the people without headphones are looking up too. It works every time.
Statues, again
Freeze! Ha. Some of you were frozen before I even finished the word.
And thenArthur teases with a false release, hidden teams split off, and the story builds towards a finale where the whole square moves as one.
Best with headphones. The pauses are part of it: that is when the square goes quiet.
Hidden teams. One reveal.
Halfway through, the group splits into four colours. Each one hears its own track, and nobody knows who else is on theirs.
RED
Stops. Holds the line. The reason the square went quiet.
BLUE
Keeps walking, past the statues, without laughing.
YELLOW
Looks up, and makes strangers check the sky for nothing.
GREEN
Watches who reacts. Every story needs witnesses.
The app does the hard part.
From the ticket to the last second, the phone keeps everyone on the same clock. Then it disappears into a pocket.

Built for a crowded square.

SYNC Collide. Two squares. One drop.
Two crowds start on two squares, with the same DJ set in their headphones. The DJ calls the moves. Then both crowds walk towards each other, and on the drop they become one big silent disco.
- Two squares, one beatEvery player picks a start square. Each crowd gets its own moves, on the same second.
- The DJ as the voiceThe set and the instructions come from the artist: jump, sit, wave, freeze.
- Phones become lightsEvery screen pulses on the beat, in the same phase. From above, the whole crowd breathes in one colour.
- Meet in the middleThe walk ends where both crowds collide. Lights out of pockets, and the drop lands when everyone is together.
- Next: two cities at onceA square in Amsterdam and one in London, on the same drop.
