To celebrate the passage of the State of New York's Marriage Equality Act, an architecture website named Architizer and a wedding website called The Knot held a design competition for mobile wedding chapels. Submitted designs had to be assembled in under two hours and not have a footprint greater than 2.4 meters square. Judges selected two winners, including this one by Guy Zucker called "The Kiss". It's made of two pieces of recycled honeycombed cardboard that must rely upon each other for structural support. You can see more pictures of this chapel, as well as the other winner, and happy couples who got married in them at the link.
