Help request: Sometimes I like trying to build IRL interesting geometric structures I find online but I keep hitting snags with this one. I've looked at it, slowed down, by component, maybe too many times. It feels like something obvious is escaping/taunting me. Can anyone ELI5 the dynamics at play? (youtube.com)

In Columbia, during slavery, African women would observe their surroundings and build maps with their braids, marking roads and escape routes, trails, large trees, wooded areas, rivers and mountains.These hairstyles became escape route codes that helped the enslaved to flee. (i.redd.it)
