How Hex Sketch works
The wall stays lit until the last minute. Then the panels flip to dark glass one by one, one every ten seconds, outer panels first, so the light pulls in toward the digits as the seconds run out. The lit panels keep flipping, one a second, so the wall is never still for long and never busy either.
The final minute breathes too. The lit panels pulse once a second. The glow behind the seconds cell warms to the palette's beat color, and it deepens as the seconds run out. You can read it from across the room, and it never turns into an alarm.
What can I change?
Pick a palette: Teal, Mono, Acid, or Cotton Candy. Set the background color, or go transparent and hang the panels over your scene. The glow lands on your video. Messages work as they do everywhere else and sit under the panels. Hex Sketch sets its own digits, so a saved timer color, bar, ring, font size, or digit font doesn't change the design. Duration, clock targets, start triggers, resume, and overtime still work.
What happens at the end?
At zero, every panel flips to the beat color in a wave out from the digits. The digits and the cell borders take the same color. Overtime lights the panels again, one a second, and counts the time up with a plus above the minutes cell. Count-up has no scale to drain, so the panels chase around the digits instead. One lights up every second.
