Meatless meal on wheels: A tourist snaps "The Diner," a mobile artwork by Texan Greg Metz in downtown Dublin. On one side of the classic Airstream-style trailer is a recreation of Christ's Last Supper -- with the disciples replaced by famous vegetarians, including Paul McCartney and Albert Einstein. People for the Ethical Treatment of Animals helped sponsor it.
