The marine-themed Expo 2012 has opened in May 2012 for a three-month run in Yeosu, South Korea. The icon of the Expo is “Big-Oâ€�, a landmark constructed to give visitors an insight into the expo’s theme, including experience zones hosting large-scale events and cultural performances.

ECA2 – a French-based company specialized in creating and producing major events and shows around the world – was in charge of designing the entire “Big-Oâ€� show as well as the O structure. The artistic and technical production of the show was also part of ECA2 mission.

During daytime the “Big-O� is a giant sculpture that will remain after the Expo as a symbolic landmark. By night, it is the centerpiece of a unique show that embraces the Expo’s themes.

The O itself features a water screen inside the outer rim, which shows films and other videos. The outer rim also produces special effects, such as laser shows.

ECA2’s team designed the O as a mysterious object that could have emerged from the ocean itself. It glints in the sunlight like a jewel over the lagoon. Modern materials such as concrete and steel are harmoniously combined to lend the structure an almost organic appearance.

For the “Big-O� night-time show, the Medialon show control system synchronizes hundreds of devices and special effects, creating an immersive show that plunges the audience into the heart of a sensory narrative.

One Medialon Manager V6 PRO show control software allows controlling and synchronizing the following:

Water:
- 24x moving water cannons (360°)
- “Cascade Screen�®, a 45-meter high water curtain which is the biggest and tallest one ever built in the world
- hundreds of water jets

Special effects:
- 24x flame generators
- hundreds of mist nozzles
- 5x lasers

Lighting and video:
- 58x moving heads (1 500W) in weatherproof casing
- 6x video projectors (35 000 lumens)

[The “Big-O� show is definitely one of the main attractions at Expo 2012 where millions of people from around the world will to visit.
