# Category covers

Original geometric SVG artwork created for Nolia / HiLo. These illustrations do not use emoji, icon fonts, external photographs or a randomly selected game card.

The source geometry is maintained in `tools/generate_theme_covers.py` and `tools/october_theme_covers.py`.

The October set includes distinct illustrations for animals, birds, food, games, films, songs, sports, islands, lakes, rivers, mountains, buildings, bridges, ships, space missions and the three Halloween categories.
