In recent days I have rewritten the algorithm to generate the colors for the LED strip.
The problem of previous implementation was that it only supported a maximum of 120 LEDs with a fixed arrangement.
With the new algorithm up to 320 LEDs are possible.
The type of the WS2811 LED strips that I use, this corresponds to approximately 5.3 meters.
This length would theoretically suffice for a screen with a diagonal of 72".
For now on, the arrangement as well as the number of LEDs can be freely configured by the user (more or less).
