Sounds line a shady drug-addicted character in a questionable part of town. But no, LOL. It’s a tessellation pattern accomplished with just one line!
Can’t get enough of those Louis Cubes. They show up every where. It’s a universal pattern, found in just about every culture across the planet. I’ve posted quite a few over the years. This one is a single vector with 12 corner points arranged in a spiral. It is built using symmetry system P3, a grid of three way rotation points, three different ones.
On a zoom-out of the images, it sort of turns grey, as the complementary colours neutralize each other.
Below, a selection of Louis Cubes I’ve done over the years.
