This week's roundup includes a giant inflatable dome in Los Angeles, underground subway-theme decor and an illuminated diamond showcase in New York, and personalized wearable data in San Francisco.

Creative Technologies and Production Club created a variety of animations in the world's largest inflatable dome for the sixth event in the traveling electronic dance music-focused Dot Party series—created by Minecraft mogul Markus Persson—which took place at the Los Angeles Memorial Coliseum in June. The 69-foot-tall, 200-foot-diameter dome held 2,500 people who partied to DJ Snake and Skrillex and was lit up by a 360-degree mapped projection that featured constantly changing animations.

Eventique produced the launch event for Forevermark's "A Diamond Is Forever" campaign revival, which took place October 28 at the Stephan Weiss Studio in New York. The event featured an eight-foot rock structure that showcased the diamonds in small, illuminated caves closed with glass windows.

For those looking for in-office Thanksgiving-theme catering ideas, Santa Monica-based Sweet Rose Creamery offers holiday pies with a twist. The seasonal ice cream pies come in flavors like Brown Sugar With Butter Pecan.

For the debut of the Balmain for H&M launch, the Swedish fashion brand hosted a party on October 20 at 23 Wall Street in New York. Bar areas were largely industrial and contemporary in aesthetic, with mock numbers mimicking the subway ticket concept. Overhead hung a back-lit screen that served more a purpose of fantasy than function: diagrams mimicked a train station route and its many stops.

In addition to the traditional bar setups, large vitrines featured images from the Balmain for H&M campaign. Again, the visuals were in keeping with the subterranean vibe of the event and modeled after advertising found throughout mass transit walkways.

The Elizabeth Glaser Pediatric AIDS Foundation hosted its 26th annual "A Time for Heroes" family festival on October 25 at Smashbox Studios in Los Angeles. For new sponsor King of Harts, organizers set up an area meant to resemble a campsite in Lake Tahoe. The booth included a s'mores-making station.

Oracle's OpenWorld Conference took place at the Moscone Center in San Francisco October 25 to 29. Mosaic and Invisible Light Network's "Voice of Data" installation let guest create a new kind of wearable data: By sharing a personal statement into a microphone, guests created an algorithm that was translated into a design, which was laser-cut into branded leather bracelets. Some guests left their bracelets behind to display them in the "Future Meets Fashion" gallery.

Orlando-based Totally Mod Event Furnishings recently launched First Class Session Seating, a new line of seats designed to provide comfort and convenience during long meetings and conferences.
