Bruno Munari was among the most inspirational designers of all time, described by Picasso as ‘the new Leonardo’. Munari insisted that design be beautiful, functional and accessible, and this enlightening and highly entertaining book sets out his ideas about visual, graphic and industrial design and the role it plays in the objects we use everyday. Lamps, road signs, typography, posters, children’s books, advertising, cars and chairs – these are just some of the subjects to which he turns his illuminating gaze.

I like the way faces are being presented in Munari’s work. The drawings from his book Design as Art could be a useful exercise to get me started with the creation of masks. Look into My Eyes on the other hand is a great way to present these masks in a book format. They have elements of interactivity as well, with each of them having die cuts of eyes and mouths. These elements of the faces remains constant while the faces change and when layered, the eyes could change colour. I find this book so simple yet brilliant.
