A flip clock — more exactly a split-flap clock — has each digit printed on a card hinged at the middle. As the number changes, the top half of the card falls forward to reveal the next number while the bottom half swings into place. This one reproduces that fold, with a dark card, a thin hinge line and a clean white numeral.
Digits that change quickly, such as hundredths on a stopwatch, switch instantly rather than fold, so the display stays legible. The flip animation is saved for the digits that change slowly — the seconds, minutes and hours — which is when it looks best. It is a popular full-screen clock for desks, classrooms and second monitors.

Questions
Can I run the flip clock full screen?
Yes. Press F or the Full screen button and the clock fills the display.
Why don't the hundredths flip?
They change too fast for a card to fold, so they simply change. The slower digits get the full flip.
Does it show AM and PM?
In 12-hour mode a small AM or PM label appears at the corner of the first card.
