Who turned Buckingham Palace into a block of flats?

For many watching – or at least those on Twitter whinging – the highlight of Sunday's Jubilee gig was the visuals projected onto the Palace as Madness played "Our House".

As the band took to the roof, the crowd below saw the façade of the 300-year-old building transform into a block of high-rise flats, which then became a row of redbrick terraced houses and revealed several interior shots, including revellers dancing in the rooms within.

The creative display was achieved by Trunk Animation, the BAFTA award-winning company behind music videos for the likes of Elbow ("Open Arms") and Jubilee performer Sir Elton John ("Million Dollar Piano"). Trunk utilised numerous animation, live action and projection techniques to complete the visual performance.

"All the contours of the front of the Palace were digitally mapped and we executed some pretty imaginative things with the technology to fully exploit this amazing backdrop, which is the perfect projection screen," the team from Trunk told the art website Artlyst.

As well as the graphics, 30 high-powered projectors were used in order to turn the eastern facade of Buck Palace into an all-swinging, all-dancing art piece. All that was missing, thanks to his unfortunately timed bladder infection, was a close-up of the Duke of Edinburgh's face when he saw his manor transformed into a block of flats.
