Video solutions company Technical Direction Company (TDC) has turned the facade of St Mary’s Cathedral into a huge 75-meter backdrop of an imaginative representation of Christmas and what it means to Sydney.

TDC created astonishing giant 17,640,000 pixel animated images using 264,000 lumens of projected light to illuminate the facade. To manage the full HD content images, TDC’s impressive hardware needs massive processing power – 2 terabytes of content management, 48 cores of processing and 144 gigabytes of RAM.

Michael Hassett, managing director at TDC said: “TDC projection video designers created special code and electronics so that the entire system is ‘virtually wired’ and controllable using an iPad device.

“Remote monitoring is something TDC has been perfecting for a number of years. It allows for rapid programming, fixes issues remotely in real-time, uses a CCTV camera on-site to see what’s happening and allows scheduling of different shows and operation of each days events.”

“Projectors can be turned on or off or even climate control systems can be activated for heating and cooling of all equipment – let’s face it, Sydney can get hot sometimes,” said Steve Cain, head technician at TDC.

Event content, original content and production was by AGB Events. “The animations have three themes based around life and light,” said Anthony Bastic, director at AGB Events. “TDC are back this year with bigger and brighter projectors. Their expertise enables us to have unlimited creativity with our artwork.”

In its sixth year, Lights of Christmas presented by Payce, is a public celebration generously hosted by the Catholic Archdiocese of Sydney at St Mary’s Cathedral and AGB Events, creating extraordinary experiences.

Merry Go Round returns this year to the landmark Commercial Travellers Association Building in Martin Place.

Using video projection from TDC, the giant curved concrete façade takes shoppers and local workers on a journey. The building appears to spin and pop as the cast of dancing robots and singing mechanical animals swing into action, before the building packs itself up and blasts off into space as a flying saucer with Christmas lights. The building is the perfect canvas for the artistic work by Ample Projects and runs until 25 December 2015.
