Pyrotechnics at CitiField

So explain to me the difference between fireworks and "pyrotechnics"? These were the "pyrotechnics" that were shot off at CitiField. There are no "bursts" or flower-type fireworks, no big booms at the end -- it was just a bunch of colored lights that rippled around the roof of the stadium -- similar to what you would see at a concert. Boring, but kinda cool at the same time. Oh well.
