If, like me, you delve deeper into tubular frame chairs, you’ll see all sorts of connections and relationships within the “tubular frame collection.” For example, in Cheese, it’s the visible way the backrest is attached. That triangle of attachment points can then become a face. I started with Cees Braakman’s SB01. It turns out that many other designs also have these facial features, see Family Portrait III, which I recently made. I’d already noticed that the number of (visible) attachment points varies considerably. I made a game about it myself, including a die. The ‘family of attachment point variations’ then becomes the Family Dice.
