In this movie Dezeen filmed with Mischer’Traxler at Clerkenwell Design Week, the Austrian design duo talk to Dezeen editor-in-chief Marcus Fairs about their Idea of a Tree machine, which makes benches and lamp shades that are all unique records of the sunlight conditions on the day they were produced.

First shown at their graduation from the Design Academy Eindhoven, the solar-powered system rotates a mould to wrap thread round itself, first drawing the cord through a tank of glue and a tank of dye.

When there is more sunlight the mould spins faster, so the material builds up thicker and in a lighter colour, meaning the resulting piece is striped with the passing of clouds and moments of bright light.

The items are priced by length and pieces made in the winter are shorter to match the days.
