ns-ui
An ambient ASCII flow-field background — a fixed set of tracer particles ride a time-evolving 2D curl-noise velocity field, each glyph's direction ('-', '|', '/', '\\') and trail alpha encoding its heading and speed, with the pointer stirring a local swirl instead of painting or repelling.
Use when Pick background-ascii-flow when the field should read as genuine fluid motion — particles with continuous position and velocity, glyph direction encoding heading — rather than a per-cell sampled scalar (background-ascii-plasma) or a persistent cursor-trail grid (background-ascii-wake).
