A full-bleed ASCII hero driven by a live Gray-Scott reaction-diffusion sim, inking only the migrating chemical fronts (the gradient ridge of the V species), so self-organising worm-like fronts crawl as thin bright lines across an otherwise empty field, with the pointer injecting fresh reagent that nucleates new fronts.
