Firework

A terminal Firework animation engine and ASCII art CLI written in Go, built with Charm's Bubble Tea and Lip Gloss TUI libraries.

Note on GPU-Accelerated Terminals

For the best animation experience, use a GPU-accelerated terminal emulator such as Kitty, Alacritty or similar. While not required, these terminals can provide smoother and more vibrant visuals for the firework animation.
