If you happened to get curious and changed the particle count to 400 or so, you saw
something disappointing. An even "flattened cone" look to the confetti, making it look
way too perfect and ruining the illusion. We can fix that by mixing a few effects together.

Why click a button repeatedly when you can have code do it for you? Shoot some firework
of confetti from the sides of page so you can still read the content in the center.

The effect is not limited to crazy rapid fire of confetti though. You can create a
wintery mood with gently falling particles across the entire page.

But if you are into crazy rapid fire of confetti, what could be a better use than
to show everyone what you are all about? Tell people where you are from with two
confetti cannons from either side of the page.

But if you just hate confetti all over the place, there's something here for you
as well. You can limit where the confetti appear by providing your own canvas element.
