Here is some code that draws fireworks on the canvas either automatically or by user input. Please try it out and see what you think.

Answer 3

It's a very nice code and visual effect. Give the option to program predefined patterns with simple variables like explosion height, radius...
It would be the editor of your personal fireworks show.
You can also add an option for live firing while the predefined pattern is being launched.
Add some socket connection to hook it up to a real fireworks firing terminal and give birth to new generations of Tchaikovsky accompained fireworks directors.

Although it may sound strange i'm really serious about that: it's an interesting doable product.
