The Guardian reports on a playful man bites dog story from Dutch design firm Moore: a book that judges potential readers by their covers. The prototype uses facial recognition to identify expressions, and will only unlock the book if it finds a neutral attitude, keeping at bay both the skeptical and the overenthusiastic. Designer Thijs Biersteker explains the project as an attempt to curb his own cynicism: “I often worry about my scepticism and judgement getting in the way of my amazement. Judgment should never hinder the relentless enthusiasm of seeing things for the first time.”
