If you like your buildings to look like out-of-this-world 3D graphics, you'll really dig these.
Sydney's landmarks have been illuminated with a sea of colour for Christmas, with large scale video projections bringing fresh light to parts of the Australian city.
The sandstone front of St Mary’s Cathedral becomes a 75-metre (246-yard) canvas for a collage called "Lights of Christmas," sharing what the holiday means to Sydney. The size of the images are massive -- they're sized at 17,640,000 pixels, with 264,000 lumens of projected light used to illuminate the facade.
Down the road, the curved Commercial Travellers Association building in Martin Place is given new purpose as a merry-go-round, transforming into a wrapped-up present, before packing up and flying off like a giant saucer.
Behind it all is the Technical Direction Company (TDC), controlling the projections via an iPad, hooked up to an almighty bit of computer hardware -- featuring 48 cores of processing power and 144 gigabytes of RAM to handle the graphics. Yowza.
If you're in Sydney, Australia, you can catch these projections until Dec. 25, before they pack up and fly away -- probably not as a flying saucer, however.
