American here (sorry), so yesterday was 4th of July, which equals fireworks.
So I had a little fun with Construct Particles and created some simple fireworks:

Note: I've had several people mention or ask me to put them in color. I went with the 1 bit theme for this one as I'm working on a game right now with that same theme (click the dude drinking coffee to link to that game)
