All of this talk about electronic fireworks and I almost forgot about a great example near my house.
A restaurant/bowling alley has some great animated fireworks in their parking lot. The attached picture is from google maps so it’s not super clear, but you can kind of see the light pole in the middle. Pole goes up as you would think, and the burst is basically a spoked sphere. Several rods are sticking out with lights along each mini pole. When they are on, they look pretty good.
