These amazing single line drawings by Croatian artist, Paolo Ceric, are created using only one line that expands from the center of the image in a dizzying spiral. He creates the illusion of depth and form simply by expanding or shrinking the width of the line at certain points. The end result are these beautifully soft and textural images that seem to vibrate off the screen. Paolo’s work is based on amazing photographs he uses as source material. He provides source credit for this work on his Behance site here.
