Ok here’s my fireworks display…
MEGA 2560 with 16X15 ws2812b array
As good as the real thing JP.
Ooops… typo… 16X25 array.
For that video, I changed my max brightness to 32 and still got that ‘overexposed’ look !
At that level, the dark blue background and twinkling stars effect disappear.
For most on this community it is clear that I ‘borrowed’ the original code from @Mark_Kriegsman but I should have been explicit about that !
Thanks Mark for that and so many other little gems that get us going !!
@JP_Roy Do you have a link to the code? I saved a link to Mark’s demo video of fireworks, but not the code.
I find it’s better to really light up the background when shooting video, I use 3x 100W equivalent daylight fluorescent lightbulbs shining on a glossy white cardboard to make a bright white background for video.
@JP_Roy Nevermind, found the code a few posts down. 
Looks like we’re all going to be ready for 4th of July this year!
Awesomesauce!
For the curious or the maniac…
Just pardon the very poor programming style and do show off your improved version !
That’s very cool! I’ve got a couple of 16x16 matrices I haven’t found a use for… This could be it. Thanks JP
