Drawing inspiration from forms found in nature, artist Rogan Brown uses a scalpel or laser to cut intricate patterns into hundreds of microlayers of paper. (The cover features a detail from his paper sculpture Kernel.) As new technologies increasingly dominate the popular culture, transforming the way people tend to see today, Brown fears an erosion of the human ability to contemplate art, nature, or anything else. To counter this loss, he creates sculptures whose sheer abundance of detail makes them impossible to comprehend in one glance; viewers are obliged to move closer and study the work in order to take it in fully.
