How does a binary clock work?

Answer 1

The blinking lights of the binary clock mark out the time using rows and columns. With 3 different brightness settings. The binary clock uses 6 columns of LEDs each representing a number of value from 0-9. The first two columns on the left represent the hours, middle 2 being minutes and the right hand 2 as being seconds.

Each columns value is calculated by which LEDs are lit. Well that’s it I’m lost. Just trust us on this one that its just cool to have one – even if you cant work out how to tell the time on it.
