Nokia partnered with fashion label Fyodor Golan for London Fashion Week, to create the world's first interactive skirt made up of Nokia Lumia 1520 smartphones. This is a new take on wearable technology. The innovative skirt uses static pictures captured by the phone, or live feeds on the 80 screens that adorn it - allowing it to change around the wearer and her day. Images on the screens change color as the skirt moves, creating a shimmer effect simulating the realistic tactile character of actual fabric. This is achieved through a purpose built app that utilizes global positioning, to ensure the shimmer happens in line with the model's movement.
