Hi Hans,
I don´t know what to say. Really, I´m speechless!
It is exactly what I was looking for and even more. To be able to set various parameters is great (had some funny color issues by tweaking them too hard).
Compared to my quick and dirty, copy and paste sketch, yours is a lot of clever and hard work. Many thanks for that!
There are two additional things I would like to implement.
Which line I can change to have the LED not stay on after pulsing? So after the pulsing the LED goes off. But it is not essential.
The second things is, the code is so complex, I don´t know where to put a push button command and how to have the effect play like 3 times after pushing the button?
It would be nice to push a button, have the effect play 3 (or so) times and after pushing it again, have the effect play again for 3 times. Will it still be shooting at random places then?
