A clock for the 0b1010 crowd.
Binary Clock renders the current time as columns of glowing LEDs. In BCD mode every decimal digit gets its own 4-bit column (8-4-2-1 top to bottom) — the classic binary clock layout. Switch to true binary and hours, minutes, and seconds each become a single 6-bit column you read like a register.
Optional live labels under each column show the decimal value while you learn to read the lights. Hide the seconds for a calmer two-group layout, flip to 12-hour with a localized AM/PM chip, and recolour the whole glow with one accent parameter.
