Binary Clock

Displays the clock time in binary representation

Description

Time is displayed as 6 columns of LEDs in the form HH:MM:SS

Thus, the included screenshot image would represent 03:49:27, because:
the first column is 00 binary = 0
the second column is 0011 binary = 3
the third column is 100 binary = 4
the fourth column is 1001 binary = 9
the fifth column is 010 binary = 2
and the sixth column is 0111 binary = 7

For another example, check out the help section of the downloaded file.

Controls:
Use the menus to change the LED color, toggle between military (24-hour) and civilian (12-hour) time, and view the help notes. Shortcut keys work too.

Examples:
>> binclock; % starts the clock with blue LEDs (default)
>> binclock([0 1 0]); % starts the clock with green LEDs
>> binclock(rand(1,3)); % starts the clock with random colored LEDs

Works nice.

Fun! I've got the real clock on my desk (my real desk, not my computer desktop). Google "Anelace binary BCD clock" for example. It's fun to watch people puzzle over the display until they figure it out. Now I can do the same on my (computer) desktop. :-)

Very cool clock, nice job!

Update: I reworked this clock to use nested functions and a timer rather than persistent variables. Now the user doesn't have to close the window to work on other things.
