Katharina Mischer and Thomas Traxler's machine makes lampshades and is powered by the sun. The thread is pulled through ink, glue, and wrapped round a mold. The sun's strength controls the speed of mold rotation. The thread varies in colour intensity, depending on how long it spent in the ink. At the end of a day, the lamp shade can be 'harvested' and the colour variation gives a graphic representation of the days weather.
This spider-like light knits it's own lampshade, when the light is on. The machine runs slowly, so it hardly seems to be knitting. The shade takes several months to be completed.
