I just woke up on July 4th and my project was... FEATURED!! Thank you everyone! I won't be able to respond to all the comments, but I'll try to read them all. And I'll keep improving this! Thank you!!!

I will be adding more features and fireworks, so keep checking in! And yes, I did launch 2000+ fireworks in testing. xD

Notes and Credits

Thanks to @MasterOfArithmetic for the HSV to RGB conversion and to @djpro for the text engine in the intro. Credit to @TheRandomDog for one of the songs. (I coded the fireworks and recorded the sound effects).

Type "US" (press U, then S while playing the project) for an ULTRA-SPECIAL surprise!!!

It's much better. :)

100% Pen (except for the variables, of course; I was too lazy to get a pen text engine).

UPDATE 10 July: Added random colors back in (no longer 4th of July).
UPDATE 8 July: Really sorry Canadians, but removed Canada flag because this WAS originally meant for American Independence Day (it was featured on it), and I am getting too many requests for other flags (mainly Australia). If you want to make your own, go here:
UPDATE 4 July: FEATURED!!! Added many features, including ultra-special flag fireworks (one for 4th of July, one for Canada 150). Thanks everyone!!
UPDATE 2 July: Added another type of firework, and added clearing of onscreen fireworks that occurs every 50 fireworks because of possible lag.
UPDATE 30 Jun: Added one more type of firework.
UPDATE 29 Jun: Added three more types of fireworks and made them only red, white, and blue!
