Polish animation duo Katarzyna Kijek and Przemyslaw Adamski have a knack of manipulating everyday materials in ingenious ways - from their stop motion work with cut-up paper for Oi Va Voi, to their remarkable video for Polish jazzer Tomasz Stanko, created from 1km of yarn and a bunch of flashlights.

But Kijek / Adamski's video for Japanese artist Shugo Tokumaru arguably surpasses anything they've done previously. In keeping with the songtitle Katachi - Japanese for 'shape' - they've created a physical timeline of ever-changing shapes, with approximately 2000 cutout silhouettes. Katarzyna and Przemyslaw describe it as "an everlasting chain of convulsive memories".

Not only is it a technical triumph - the shapes were made from PVC plates, using a computer-controlled cutter - the progression in the video is completely mesmerising from start to finish. Brilliant.
