This week's roundup includes Veuve Clicquot's take on the Hollywood sign at a Los Angeles polo match, Dior's haunting vertical garden at Paris Fashion Week, a sandcastle replica of a Miami condo, 3-D printed event gifts at Microsoft's Advertising Week activation, and a prop-cow greeter at a Chicago burger bash.

The Hamburger Hop took place on the rooftop of Chicago's Harris Theater on September 27. A kickoff party to Chicago Gourmetโthe high-end food fest presented by Bon Appรฉtitโthe hop centers on a competition in which prominent chefs battle to create the best burger. A prop cow stood sentry at the entrance to the meat-centric event.

At his final show for Louis Vuitton at Paris Fashion Week, Marc Jacobs delivered a bangโand not just with the clothes. The October 2 spectacle at the Cour Carrรฉe du Louvre tent saw the fashion house recreating many of the sets from Jacobsโs 16-year tenure, including a fairground carousel.

Diorโs Spring 2014 show, held September 27 in the gardens of the Musรฉe Rodin and produced by Bureau Betak, used a custom-built metallic framework set that spanned 16,146 square feet. As guests arrived, they met an imposing venue faรงade seemingly inspired by Patrick Blancโs iconic vertical garden. The striking landscape (98,425 feet of creepers and 3,229 square feet of branches), reminiscent of a relic overrun by nature over time, set the tone for what was in store inside.

On October 1, a seven-foot sandcastle heralded the start of a major residential construction project in Miami. Aria Development Group celebrated the groundbreaking of its luxury condominium, 321 Ocean, with a ceremony for city officials, buyers, and friends and family. Guests gathered around the sandcastleโwhich was a whimsical replica of the forthcoming propertyโfor a toast, then headed to nearby restaurant Estiatorio Milos for a reception.

At the Veuve Clicquot Polo Classic October 5, a 70-foot-long wall of letters spelled out the brand's name and was meant to recall the Hollywood sign.

Aiming to increase foot traffic and engagement at its 2013 Advertising Week activation inside the lobby of the Times Center in New York, Microsoft invited clients to touch, hear, and experience the companyโs computing products and services from a consumer standpoint. To highlight a creation theme and the software company's partnership with 3-D printer MakerBot, attendees could watch as the machine printed take-home gifts such as a comb or a bracelet.

At the Human Rights Campaign National Dinner October 5 in Washington, a multitiered stage backdrop of three 28- by 50-foot video screens showed inspirational videos of the H.R.Cโs work in Washington, memes of its logo, and live feeds of the nightโs speakers and performers.

MaxPoint, a digital advertising agency, promoted its line of work with a drolly somber activation during New York Advertising Week. On September 23, a procession inspired by a New Orleansโstyle funeral wound through the streets of Manhattan. In addition to holding signs with phrases such as โInk Fades Awayโ as well as the stunt's official hashtag, #GoodbyePrint, the performers carried red umbrellas, twirled handkerchiefs, and played horns and drums. Barkley Kaplak Agency produced the event.

Accommodations booking site Airbnb found a unique and experiential way to highlight its offerings to consumers in Los Angeles. Called Hello L.A., the five-day campaign had celebrities host and design pop-up listings and experiences in iconic places around the city. Moby hosted an event at the Viper Room and shared unreleased tracks from his new record, Innocents. At the pop-up, a so-called "silent disco" provided the soundtrack for guests in headphones.
