Uninstallation

    make uninstall

How to read the clock?

The fibonacci clocks are made up from 5 blocks going in a spiral according to the Fibonacci sequence. Starting with the "5 block", then the "3 block", "2 block", "1 block" and another "1 block".

Every block can have 4 colours - Red, Green, Blue and White:

• Red blocks = Hours
• Green blocks = Minutes
• Blue blocks = Both hours and minutes
• White blocks = Nothing

Let's try it on an example

For hours we will sum up the red and blue blocks:

5 + 3 + 2 = 10

NOTE: We also need to remeber that clocks can only show time in 12-hour format, because the sum of all blocks is 12 (5 + 3 + 2 + 1 + 1 = 12)

For minutes we will sum up the green and again blue blocks:

5 + 1 = 6

Because the clocks can only show numbers from 0 to 12. The minutes are divided into increments of 5.

That means we need to multiply minutes we counted (6) by 5.

5 + 1 = 6 => 6 * 5 = 30

NOTE: This obviously also means that the precision of these clocks is 5 minutes (10:00 -> 10:05 -> 10:10 -> ...)
I have set it up to round XX:02 down to XX:00 and XX:03 up to XX:05 and so on.

Now we have our result: 10:30

I have been inspired by this project by user pchretien, he covers and explains the clocks even better than this README.
