Each letter is a close-up of gyri (bumps) and sulci (grooves) found on the surface of the human brain. The letters were all found within the brain photographs shown on the right. Some of the patterns were rotated, flipped upside-down or enlarged. This project was inspired by the "Butterfly Alphabet" created by Kjell B. Sandved.
