Split-Flap Board

No. Only what changed flips. A data refresh turns just the characters that moved; resizing the visual or switching the theme repaints the board without re-flipping it. Every character sits on its own drum that only turns forward, so a change walks through the characters in between, and the board settles in a cascade you choose: sweep, curtain, row by row, scattered or all at once, at the speed you set.

Time and number columns use digit drums, so a clock ticks in one flap the way the real modules were built. Accented letters such as Č, Ř, Ö, Ł and É are added right next to their base letter only when your data uses them, so an English board keeps the short ring and settles fast.

Yes. Status words become On track, Watch, Problem or Done from word lists you can edit, with English, Czech, German, French, Spanish and Polish built in. Or bind a measure to Status Measure: text such as Delayed goes through the word lists, and a numeric code goes through per-class code lists with exact codes, ranges such as 5 to 15 and comparisons such as greater than 30, printed as your own labels. A board follows your business rules without a calculated column.

Status never depends on colour alone: the word stays on the board and each class lights a lamp of its own shape. Write {green}, {red} or {yellow} in the text for a solid colour flap.

Long lists page themselves, with a page indicator and a progress bar, and keep paging through automatic page refresh. Hovering or pressing P pauses; a mouse left resting on a wall screen stops pausing after 20 seconds, and Page Up and Page Down turn the page. The header carries a live clock and date in the viewer's time zone, UTC or one of 20 cities from London to Los Angeles, daylight saving included, in 24 or 12 hour format.

The board is sharp on a 4K screen and readable on a small report tile, and an optional one-pixel drift protects OLED screens from burn-in. It is sound-free by design, so it is welcome in an open office.

Three layouts cover the wall screen: a departure board, a message board that word-wraps one message per page for a reception welcome screen, and KPI tiles with a big value and a status line. A plain table style shows the same data calmly, with no modules and no motion, for the boardroom.

Four themes have their own character: a teal terminal, the classic black airport board, a gallery white board and a blue station board. Every colour of the board, flaps, lamps and labels can be changed, and shadows and the title rule switched off.
