I just set up a new site for one of my mothers projects: "Baum der Religionen" (Tree Of The Religions) - a project to improve the understanding and tolerance between different cultures and religions.
The idea is actually quite simple: Several different apple sorts were grafted onto an apple tree. Each of the seven apple sorts represent on of the seven world religions: Christianity, Judaism, Islam, Hinduism, Buddhism, Zoroastrianism, and Baha'i.
