fireworks design

Does anyone know if there are fireworks designers? I wonder how that works, I’d be interested to see what that design process is like.

Here is a Nat Geo. Megafactories video on how they make them, - YouTube

And if you see related links there is another series by Nat Geo. Called Pyros

Apparently a lot of secrecy among pyrotechnics about how certain visuals are achieved.

Ahhh, awesome!
