London Design Festival: London designer Paul Cocksedge has made a giant chocolate QR code that visitors to The Dock during the London Design Festival can scan to get a free gift (or you could just scan the image in the bottom of this story).

Cocksedge worked with Hotel Chocolat to create the installation as part of Designs on Chocolate, a project pairing five designers with five chocolatiers. Following a visit to the company's factory, he decided to use nearly of their 1000 chocolates to make an interactive mosaic.

"I wanted to leave these beautiful pieces of chocolate as they were, instead of creating an object simply to be looked at, and so losing the whole idea of taste," Cocksedge says. "The true art of the chocolatier appeals to your palate as well as your eyes, and through the process of placing these exquisite pieces in various patterns, the project started to grow.”

Scanning the QR code on a smartphone or tablet leads visitors to the Hotel Chocolat website where they are rewarded with a voucher, to be exchanged at the company's flagship store in Covent Garden for a limited edition chocolate box that's been specially made for the London Design Festival's tenth anniversary.

"The idea is to create a pattern which is seemingly random but which, through the subtle introduction of technology, becomes something altogether new, the start of a journey," explains Cocksedge.

Designs on Chocolate will be on display at The Dock, Portobello Dock, 344 Ladbroke Grove, London, W10 5BU until 23 September. Photographs are by Mark Cocksedge.
