The Challenge: “What does the word “intricate” mean to you? It could be the deep, fibrous bark on the ancient oak tree in your yard. Maybe it’s the robin’s nest under construction near your window — that ornithological engineering marvel of mud and twigs. It could be the treasured piece of needlepoint your grandmother crafted, or maybe a drawing you made. It could be the leaves falling from trees in the Southern Hemisphere — the wind arranging them just so on your lawn.”
There’s nothing quite as intricate as the details shown in the architecture on these buildings in Barcelona, Spain.
