To celebrate the return of Doctor Who and as part of the brand’s 60th anniversary celebrations, BBC Studios has teamed up with Back Market — the global online marketplace for refurbished tech — to create an installation on London’s South Bank.

The 7-by-9-foot anamorphic, 180-degree interactive instalment, Art of Regeneration, is made out of regenerated technology. It has been handcrafted by Global Street Art using hundreds of discarded devices. The sculpture shows the current Doctor, David Tennant, seamlessly regenerating into the Fifteenth Doctor, Ncuti Gatwa as a physical embodiment of the Doctor’s ability to regenerate into a new physical form.

On Friday 8 December, the TARDIS joined the sculpture as part of the installation.

On Saturday 9 December at noon, Doctor who fans are invited to come in cosplay for a photo call.

On Sunday 10 December, fans can come view the Fourteenth Doctor’s sonic screwdriver and see Fifteenth Doctor’s sonic screwdriver for the first time.

Back Market and BBC Studios’ Doctor Who sculpture installation, Art of Regeneration, is available for free public viewing from 8 to 11 December at the Queen’s Stone on the South Bank’s Riverside Walkway, next to the OXO Tower. After that, the sculpture will return to BBC Studios’ Television Centre headquarters, where it will live until it’s dismantled and the technology recycled.
