On 5 December 2009, a massive celebratory event was held at the Anantha Samakhom Throne Hall in Bangkok King Bhumibol Adulyadej of Thailand's 82nd birthday. Spanning a week long, the star of the event itself was the throne hall which effectively became the backdrop of a video installation show, combined with a huge orchestra cast of 128 international musicians and a choir of the best singers in Thailand.

The nightly one hour show combined past and present images of the king, his social projects, as well as custom made 3D animations of natural and cultural heritage of Thailand. At least one million people attended the show.

Rental partner CT was contracted by Kaiser Communications and Fresh Air Festival Co to provide the projectors and video link for the event. Berlin artist was commissioned to provide content for the show. , a company specialized in digital art, was asked to manage the projection, 3D mapping and media broadcasting for this event.

For this 4D visual light & sound show the team wanted to project video on to the external facade of the throne hall building, a two storey building in the style of italian renaissance/ neo classic architecture. It measures 112.50m in width and 49.50 meters in height, with a large dome in the centre surrounded by six smaller domes.

CT Asia worked with Kaiser and Fresh Air for over 3 months on the project. "The huge surface of the throne hall made it almost impossible for ordinary projectors to cover and still achieve an acceptable level of brightness," said Rony Xu, General Manger Singapore, CT Asia. "A demonstration was done for the client and they agreed that only the Barco XLM HD30 is up for the task."

A total of 4 Barco XLM HD30 was used to cover the entire front facade of the throne hall, centrally managed with Barco's Projector Toolset. The video link from the playback system to the XLM projectors was done through an optical fiber system and a DVI matrix system was employed to provide switching between primary and backup playback system.
