Time – The dying arrow

SketchesArrow1SketchesArrow2

The dying arrow is a project made of red and orange LEDs, that are all HIGH , and then turn one to one LOW. Such as a neon symbol not functioning well in bars, the "dying arrow" shows the passage of time where life goes off.

I really enjoyed the rough aspect of my prototype, where you can see the wire, as well as the reflection of the red LEDs on the shiny black paper.
I want my piece to preserve a rough aspect as a mechanism of the old times, and I will put mirrors around it to enhance its life and death.
I had a hard time trying several possibilities in my code. It is not finished yet, and need to work on it a lot more! But it shows all the LEDs on HIGH with two of them blinking.
I didn't use arrays because I couldn't get it working as I wanted.

13 LEDs are on HIGH at first, then they blink and pass on LOW one at a time
