| Gaia's Daisyworld concept. An imaginary world completely covered with the seeds of two types of flowers, white and black. The black flowers are better at absorbing light from the sun; the white flowers are better at reflecting light. In cooler conditions, the black flowers proliferate, and because they retain heat they eventually warm up the environment to a point where the ability to reflect heat becomes advantageous, allowing the white flowers to proliferate. |

| "Dehors" (Outside) by Yves Tanguy. Tanguy's family came from the Finistère area of Brittany, and as a child he spent his summer holidays there. The prehistoric stone monuments left a strong impression on him, and they seem to reappear, as if in dream-like scenes, in his paintings. The artist's early career in the merchant navy may be relevant, as the scene suggests an underwater landscape. The strange symbols are similar to those found in the work of Miró, who often took the birth of the world as a subject for his paintings. |
