## JClock VIII

Interpreting the hour hand on a clock as a two-dimensional object on a plane, the hand’s tip can be seen as a complex number.
This clock converts the hour hand’s position into a complex number, sets the number’s length to the current minutes and displays it in the form $a + b \cdot i$.
The angle $\phi$ is determined by the hours passed ($\frac{2 \cdot \pi \cdot \text{hour}}{12} = \frac{\pi \cdot \text{hour}}{6}$) but has to be slightly modified because a complex number starts at the horizontal axis and turns anti-clockwise whilst an hour hand starts at the vertical axis and turns — as the name implies — clockwise.
Thus $\phi = (2 \cdot \pi - \frac{\pi \cdot \text{hour}}{6}) + \frac{\pi}{2} = (\frac{15 - \text{hour}}{6}) \cdot \pi$.
The complex number’s length is simply determined by the minutes passed. Because the length must not be equal to $0$, I simply add 1. $|z| = k = \text{minute} + 1$.
Lastly, to convert a complex number in the form $k \cdot e^{\phi \cdot i}$ into the form $a + b \cdot i$, I use the formula $k \cdot (\cos{\phi} + \sin{\phi} \cdot i) = a + b \cdot i$.

## JClock VII

This alternative clock is not really readable by human. It calculates the first 144¹ primes, assigns 60 of them to every possible second, 60 to every possible minute and 24 to every possible hour.
Multiplying those three primes for a given time results in a composite number representing said time. Using integer factorization, you then can get the three primes back, map them to seconds, minutes and hours, and by doing so calculate the time.

¹This number is the sum of 60 seconds, 60 minutes and 24 hours.

## JClock VI

This clock uses a simple clock design with the standard clock face. Red, green and blue represent second, minute and hour.
