Guy Fawkes: the last man to enter Parliament with honest intentions. (As someone said on Twitter earlier, but I've already lost who it was. Sorry, that person). Let us celebrate/flagellate the man who tried to take down British government, either by setting fire to things and making sky-flowers, or by creating virtual sky-flowers.
Embedded below is a fireworks simulator for you to dick about with. I found it via typing "fireworks games" into Google, so cannot vouch for its origin, age or truthiness. It's also more a tech-experiment than a game, as such. I can vouch for it being a surprisingly scientific recreation of creating explosions in the night sky, however.
I don't care if you tell me off for posting this. Fireworks! Yaaaaays!
