Original Clocks

 

The Backwards Wall Clock turns back the hands of time (well, sort of)! It's a wall clock that runs counterclockwise. The clock's hands (hour, minute, second) all move backwards giving the impression of gained time. Probably what ends up happening though is more time is needed to decipher the current time.

I saw this on a colleague's desk - it's a Binary Desk clock. How cute is that! It tells time in either BCD (Binary Coded Decimal) or binary. Computers store time in binary. So how does one read a BCD clock? Very carefully :)

Okay bad joke. Each two columns represents a digit on the clock. So the left two columns are the hours, the next two are the minutes, and the last two are the seconds. Each row is a power of 2. So the rows are (from bottom to top) 2^0 = 1; 2^1 = 2; 2^2 = 4; and 2^3 = 8. Adding the rows results in the corresponding time digit. So the blue clock in the image shows 10 hours 48 minutes and 36 seconds!
