Custom effects for WS2811 LED pixels

I got these back in 2018 but at that time I had no ideea how these kind of LED's where working and I abandoned them for a very long time...
Components used:
Arduino Uno
WS2811 Pixel LED's (47 led's in total sadly.. :/ )
12V power supply (I used the 12v version of the led's)
Code info:
Library used: Adafruit neopixel
Contains 6 custom animations (few of them are original with the exception where I keept some of the animations from the examples I tested out...)
Making my own custom animations is pretty painful since I'm a beginer to use these (and I don't have the best programing knowledge :( )
I may come up with some new video once I get more custom animations
PLS Note this:
My code will never be public since it's pretty messy (altough I tried to be as organized as possible + I hate my own code, I wanna do much better...) and I don't want any other users to use my effects.
