A steampunk-inspired visualization of time, represented in pure binary format (Base-2).
This is a Binary-Coded Decimal (BCD) clock.
Each column represents a digit of the current time (HH-MM-SS).
The rows represent the bit values: 1, 2, 4, 8 (from bottom to top).
Sum the lit bulbs in a column to get that digit.
If the bottom bulb (1) and top bulb (8) are lit, the digit is 9.
If only the middle bulb (2) is lit, the digit is 2.
Computers think in binary. By using bitwise AND operations (value & mask), we check which bits are active for every digit hundreds of times a second.
