I am wondering if anyone has ever found some code (as a starting place for me) for a “fireworks” animation on a single strip. I imagine the firework “exploding” on a random part of the strip and then spreading and twinkling until it fades away.
The closest I’ve seen is the Neopixel Ripple, as found at https://gist.github.com/suhajdab/9716635. I converted it to FastLED at https://github.com/atuline/FastLED-Demos/blob/master/fastripple/fastripple.ino
This is something I am planning to draw up with the particle code I just wrote.
I saw @Mark_Kriegsman or @Daniel_Garcia (I forgot) with fireworks on a matrix a while back. I wonder if they’ll be willing to post the code.
That’s be me. My backlog is getting a bit scruffy, but I’ll add that to the queue!
When it works, my memory does pretty good.

Video; no code posted back then.
As I said, I’ll put that in the queue.
Profile not found. I know you like to stay out of the limelight there Mark, but …
Yeah that … That’s what I remember seeing.
