Kellenberger–White were commissioned to work on a book for MIT Press by Dunne & Raby, a collaborative design practice. In ‘Speculative Everything’, Anthony Dunne and Fiona Raby propose a kind of design that is used as a tool to create not only things but ideas, as opposed to design that focuses on making technology easy to use, sexy and consumable.

The most dramatic aspect of the publication was the display and title font we created: Chlotz is built entirely out of zeros and ones, the fundamentals of computing. The “S”, for example, is made by turning each half of a zero outwards to create something akin to a sine-wave. Our body font is a spacious, readable sans serif that was inspired by typography created for IBM’s technical documentation: the 1956 font Letter Gothic. Together, our fonts are at once clear and intriguingly eccentric.
