Here it is: your start-of-the-week visual boost. I've found 4 images that are high in kaleidoscopic detail, with areas of intense patterning.
1- Various Pediastum from"Kunstformen der Natur" by Ernst Haeckel
This is a plate illustrating various different forms of green algae. Who knew green slime could be so pretty?
2- Illustrated fashion editorial by Good Wives & Warriors for I <3 FAKE
GWAW is an illustration duo consisting of Becky Bolton and Louise Chappell. They collaborate to create these very intense and dense decorative images. They cover everything, from magazines to chairs, and even a car.
3- Vintage Armani, photographed by Stephen Shore for Amica
4- Illustrative book detail by Harry Clarke
from "Tales of Mystery and Imagination" by E. A. Poe, 1923
Clarke was a stained-glass-window-maker-turned-illustrator. He created a large series of illustrations for Poe's work; some full colour, some monochrome and some extra page bits like this writhing, flourishing monster.
