The split-flap board for any screen.
The Clack Stack turns a TV, a tablet, or a website into a mechanical message board. Type on your phone — watch it flip across the room, click by click.
One board. Anywhere there's a screen.
These screens aren't mockups — every one is the live board, flipping right now, exactly as it looks on a wall.
Coffee shops & restaurants
Today's menu on the TV behind the counter — updated from the office, flipped into place before the doors open. Specials change with one message.
Family homes
The kitchen board that greets the house, keeps the day's schedule, and counts down to the beach trip. Everyone reads the wall, nobody checks an app.
Offices & lobbies
Welcome walls, standup times, launch countdowns, the numbers that matter — with a mechanical presence no slide deck on a TV will ever have.
On your wall, it looks like this.
Real rooms — and the board in each one is live, flipping while you read this.
Any TV becomes the board
This corner's TV is running The Clack Stack — purist mode, flipping to a new quote every so often. Guests hear the soft clack and look up.
