This is pretty cool: an app to teach you whatever you might want to know about Passover.
This comes from Chabad, the Orthodox Lubavitcher Jewish group from New York. They send out 'missionaries' ( they call them emissaries) to work among 'less-active' Jews all over the world, teaching and modeling how to keep the commandments. It is an interesting form of Judaism, very traditional in how they live and practice their beliefs, but very modern in their use of technology and social media.
