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.
Once a year - when the tree is in full flourish - the "Apfelblütenfest" is celebrated and members of all religions are invited to enjoy a relaxing time with delicious cakes, enlightening talks, and interesting people.
Check it out:
Baum-der-Religionen.de (german – work in progress)
Like my own site it is powered by Drupal and a bunch of additional modules.
I like Drupal for to things: It's quite easy to get presentable results and it is very extendable through a wide range of available modules and even custom PHP code inside you postings (if you have to).
