Damien Ludi and Colin Peillex, students at the University of Art and Design Lausanne, have come up with a rocking chair that knits as you sway back and forth.
Called the Rocking Knit, the wooden chair has gears above your head that utilises kinetic energy to knit. Each swaying motion powers the gears, which sends yarn to a knitting round. The final product is a cosy red beanie made with minimal effort (so long, needles!).
The contraption was made as part of a program that encourages students to make a machine that creates both an experience and a material good.
