To create the images for his video "Katachi" -- which means 'shape' -- Japanese singer-songwriter Shugo Tokumaru turned to two video artists from Poland. Katarzyna Kijek and Przemysław Adamski took the song's title literally and made some 2000 colourful PVC silhouettes using a computer-controlled cutter. They then used the silhouettes to create a fascinating stop-motion music video.
