It looks as though Naoto Fukasawa's latest collaboration with the Diamond, Inc. is the creation of a company called ±0 (Plus Minus Zero). Their aim is to create household items with a "spirit of fun" in much the same way that the Without Though series has (Without Thought 4, Without Thought e-Fashion, Without Thought 2?). I love Fukasawa's description of some of the reasoning behind the designs:
Rounded edges (R) are artificial creations. Squaring off the rounded edges of a piece of timber is something that we do even though we know that the edges will become rounded, either through human hands or through the process of weathering. We entrust this rounding of the edges to nature. We decided on the adoption of R2.5 – which is similar to the rounding of edges (R) that occurs naturally – as the ±0 design range’s base language because it is close to the natural R created by human hands. Your fingers automatically reach out to rub over the rounded edges of the warm, unpainted pale wood.
Product Art, their first set of products, should go on sale before the end of the year.
