This is the fireworks demo that I wrote to learn python from. I tried to see what it would also look like in rust, and I was pleasantly surprised at the results.

Here is a video on YouTube if you'd just like to review the results!

One thing this version does differently is that it moves the cursor position based on a difference of the previous draw and the current; this results in a much more optimized draw routine. You will notice the frames per second much higher and I feel the animation is a little better. It is also much easier on the CPU.

This is published as fireworks-erikh on crates.io and installs a fireworks binary when you cargo install it. This conflicts with the fireworks crate which does more or less the same thing, just done by someone else, hah. Enjoy the weird terminal screensavers I guess.

This is a TUI "screen saver" that displays fireworks on the terminal. It will display them until Ctrl+C is pressed and is designed to work with tmux, etc, to provide some bling on your terminal when you only need half of it.

Some notes:

10 fireworks are launched at start, and every 5 iterations (about half a second) a new one is launched. Fireworks trail north and have a chance of exploding on every frame. Each flare and explosion have random components to the trail and characters used. If the terminal is resized, it clears and rebuilds the scene anew.
