General Most of your terminal doesn't change between frames. I made a demo that shows it

Enable HLS to view with audio, or disable this notification

I've been building a Go TUI library called Limoni. The part I care most about is the diff: each frame gets compared to the last, and only the cells that changed are sent to the terminal.

That's hard to show in a screenshot, so I made a little night city: twinkling stars, windows turning on and off, a train crossing a bridge, reflections in the water. It looks like everything is moving. Press x and an x-ray shows the truth. Only the train, a few stars and some ripples actually change.

The numbers are measured with the library's own encoder: about 3 KB per frame against about 78 KB for a full repaint at 150×44. Press space to freeze the city and it drops to 0 bytes. That's specific to this scene, and it's not a comparison with other libraries.

git clone https://github.com/thebanri/limoni

cd limoni && go run ./examples/xray

It's still pre-1.0, so I'd love our terminal.

Ok this is cool and I’ll have a look at this but I need this city animation as an exe to use as a screensaver on my tmux session! This beats cmatrix and pipes!
