The split-flap display for any screen.

The Clack Stack turns a TV, a tablet, or a website into a split-flap display — mechanical motion, mechanical sound, zero hardware. Type on your phone and watch it flip across the room.

One display. Anywhere there's a screen.

These screens aren't mockups — every one is the live display, exactly as it looks on a wall. Press play on any of them to watch it flip.
