 * The flowjs website. Its material is what Flow does with a page: a line, and the stations a scroll

 * road and transit signage (Delve Withrington, SIL Open Font License), with Overpass Mono for code;
 * black ink on paper, one signal yellow for the stations, the current place and what one acts on.
 * At night the sign is lit: light ink on a dark ground, the same yellow.
