Or you can post your code on github 
@Marc_MERLIN it is very useful , i took the following patterns:
2, 7, 12, 15, 16, 18, 26, 29, 102, 103, 105, 107, 108, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62, 63, 97, 67, 69, 40, 47, 48, 50, 96, 71, 72, 74, 75, 79, 93, 81, 82, 83, 86, 88, 91
Just by coincidence i tried the code on 16 strips with 300 LEDs, Because your config.h file specified 16 outputs.
and it looked great imo.
Then i sorted the patterns and used the ones which looked nice and trippy.
You just canāt see the shapes of the patterns because the strips arenāt snakewise connected.
it was a lucky shot, because i canāt code
i understand a little of the code to make things work out, but thatās basically it,
I got a 20 minute video of all the patterns. itsā 1 gb
iāll post it when i get back home after the weekend.
@Jeroen_van_Dorsten itās very cool that so many of them just worked for a not square at all matrix. Glad it worked for you with almost no coding required
