"Beauty of mathematics" by Yann Pineill & Nicolas Lefaucheux.
When Jimmy was set to do something, nobody could stop him. He was tough-minded when he felt he had to be. And when he laughed, the whole world laughed, and when he cried, it rained. He was always able to get people into his moods. It was a wonderful gift. - Ortense Winslow
