Hello, i collect Blobcat SVGs i have made here. The license is public domain /
CC0 unless otherwise noted in the SVGs metadata.
  I used Inkscape to make them, so it's probably best to edit them with
that. Use raster images for displaying, the SVGs get rendered differently
everywhere.

Generate WebP images:
  ./generate_raster_images.zsh
Generate PNG images:
  ./generate_raster_images.zsh png
Generate 400 pixel wide/high WebP images:
  ./generate_raster_images.zsh webp 400

You need zsh and imagemagick to run the script.
