I couldn't wrap my head around using an irregular matrix or even blank pixels

I couldn’t wrap my head around using an irregular matrix or even blank pixels in a matrix. I modified Mark’s demo reel here. I think it works well enough. I attempted to add a second glitter effect of a different color, but it stated that it was already defined, I’m not sure how to make that work, or have glitter with a few different colors at the same time. I’m running out of time for those issues, so this will probably be the program I run at Voodoo fest, but i’m setting the time to 2 minutes between effects. Sorry for the vertical video(eww).

Looks cool. I love Voodoo. Went a few years ago… I’ll have to get back

I think it looks really nice.

I have put up a very generic tutorial on LED Mapping http://www.elec-tron.org/?page_id=1351

I made two rainbow glitter patterns that have color instead of white. One picks random colors, and the other shifts the hue of the randomly picked pixel to “glitter”.

@Leon_Yuhanov thanks for the link. I sort of under stand the layout this way, but I think I numbered it wrong, they are lined up vertically not horizontally. I could fix that part easily, but I really just don’t understand how to code it. I’m trying to run before I can walk. https://docs.google.com/spreadsheets/d/1C5AJ5tKf1d5cMCLhmk-bF5FCzGu2dHMkPSvqZ_Dy8eM/edit?usp=sharing

@marmil Thanks! I’ll test those when I have a bit of time.
