  The cosmic web (the arrangement of matter in the universe), spider's webs,
and origami tessellations are linked by their geometry (specifically, of
sectional-Voronoi tessellations). This motivates origami and textile artistic
representations of the cosmic web. It also relates to the scientific insights
origami can bring to the cosmic web; we show results of some cosmological
computer simulations, with some origami-tessellation properties. We also adapt
software developed for cosmic-web research to provide an interactive tool for
general origami-tessellation design.
