My article today is about the binary clock ! This cool and funny clock which I sometimes call Geek’s clock uses a combination of zeros and ones(binary numbers) to display hours, minutes and seconds.
They aren’t that difficult to read, it’s all about using combination of zero(light off) and one(light on). The four bit binary clock shown above has 4 rows and 6 columns. The first 2(L/R) columns represent Hours, the next 2 represent Minutes, and the last 2 represent seconds.
The bottom row in each column represents 1 (or 20), with each row above representing higher powers of two, up to 23 (or 8).
Reading them is as simple as adding the values in each column and join with added value of second column.
Cool Stuff 
There are Binary Clock scripts available for websites and real clocks and watches too can be purchased.
