Kids around the world are invited to gather in Jerusalem—without ever leaving their hometowns. How’s that possible? Simply send a digital photo of yourself to the Jewish Dream Network. The organization will arrange your photo with those of thousands of other kids to create a photomosaic image of Jerusalem’s Old City to be issued as a poster. “The photomosaic will give everyone a chance to see that in spite of the huge variety within the Jewish community, when it comes to helping Israel we can all come together,” says Tobey Herzog, project coordinator. Along with their photos, students are encouraged to send a prayer for the state of Israel, which will be placed in the Kotel on Hanukkah.

The Prayer for Peace Photomosaic project is the brainchild of Tobey Herzog, who created the “World’s Largest Rosh Hashanah Card” with the help of 45,000 children around the world. The card, which is 8 feet high and 400 feet long—slightly longer than a football field—was presented to the people of Israel on September 12, 2001.
