Carte Noire

Window of Intensity

June 13, 2013

Early in 2013 AllofUs collaborated with digital agency Work Club to transform a shop window into a unique sensory experience. 

The 5m wide window display presented a digital reflection of people at Westfield Stratford, captured in full HD. This everyday scene was then augmented and transformed using motion tracking, realtime effects, generative visuals & sound effects. These effects included motion blur, immersive ribbon-like trails that augment and complement the ambient scenery, rain drops, crystallising patterns and various lighting effects.

The closer passers-by came to the window and the Carte Noire tin, the more intense the experience, representing the intensity inside every tin of Carte Noire Instinct. The piece was live for a week and was filmed over two days capturing the public’s reactions.  Go to and join the other 900,000 people to see the results! 

The software for the piece was developed using openFrameworks. Video was captured from a hi-res security camera at a full-HD resolution of 1080p at 30fps using a Blackmagic Intensity Pro PCIe card. Motion in the scene was detected and analysed using openCV, specifically blob tracking and optical flow algorithms. This input, along with colour analysis and proximity was used to allow users to interact with the effects.
