Killer project from Archizoom founder Branzi, along with others, who together formed Il Centro Design Montefibre, to research textiles, fibres and colours. Decorattivo was intended to be an annual publication, though only 2 were published by Idea. The themes for Decorattivo 1 are UFO, a decorative system created from space objects, and amorphous designs connected to spontaneous processes, with volume 2 focussing on lines and squares. Texts are also a very definitive and well considered statement. As far as research and as a sourcebook- it is yet to be bettered!
