Terminal

Terminal — a live terminal, drawn as a model. It is the same texture-on-a-plane path the spectrogram and the recurrence plot use, so it rotates, zooms and takes a gradient like any other model; what is on the texture is [xterm-go](https://github.com/0magnet/xterm-go), a Go port of xterm.js, rendering a real terminal grid with WebGL2. That last part is what makes this possible rather than merely desirable: a terminal drawn as DOM could not be sampled into a texture at all, and rasterizing DOM every frame is not a thing worth doing. xterm-go renders into a canvas, and a canvas is a texture source. Behind it runs [websh](https://github.com/0magnet/websh), a Bash interpreter compiled to wasm over an in-memory filesystem, so this is a session you can work in and not a picture of one: pipes, globs, redirection, `for` loops, all of it rotating with the model. **Double-click** the canvas to type into it and **Esc** to give the keyboard back — a double click because a single one is how you rotate the model, and the two must not be the same gesture. Focusing it silences the app's own key bindings automatically, since Pong, the Keys module and the hovered-knob arrows all already stand aside for a focused textarea, which is what a terminal captures keys on. It can also be the BACKDROP behind another model, the way the spectrogram can.

It opens running, on the model selector, with its own knobs. Rotate it by dragging, zoom with the wheel, and turn the parameters to see what the figure does when the system changes.
