You know what would be really fun to see? Fireworks mixed with magical aether to simulate living creatures! Imagine, a firework that takes on the form of bahamut and lets out a mighty roar before exploding. Or maybe even a firework that takes on the form of a charging boar that travels a few feet before discipating. Those kinds of fireworks would be quite interesting to behold! I can see Ul'dah's Thaumaturge guild coming up with that sort of stuff!
