PHOTOS Tefillin Shel Rosh

My buddy Mike w/ Tefillin on Ben Yehuda.

The Lubavitcher Hasidim, have made a particular effort to promote the mitzvah of Tefillin among Jewish males. They often set up vans, known as Mitzvah Mobiles, in neighborhoods frequented by Jews, and ask men who pass by: "Are you Jewish?" If the answer is yes, they continue: "Did you put on Tefillin today?" If the person says, "No," they invite him inside the van. First they put on the box that goes on his arm (for right-handed people, the Tefillin go on the left arm; left-handed people wear them on the right arm) and wrap the strap around the arm seven times. Then the other box is put on his head. They lead him in the recitation of the blessing over the Tefillin, and in certain other major prayers, such as the Sh'ma. -- [from www.jewishvirtuallibrary.org]
