American postminimalist artist Richard Tuttle (born 1941) has worked in close collaboration with the Kunsthaus Zug in Switzerland as its informal "in-house artist" for almost 20 years now. Through fragile, mostly small, subtle paintings as well as sculptural objects and three-dimensional installations, Tuttle continues to explore special features of the museum's architecture and selected works from its collection, exploring larger questions of endurance and continuity, rhythm and repetition across cultures globally. Use of Time is a slim, elaborately designed artist's book--published in a limited edition of 850 copies--with 18 cards loosely bound by square knots and round grommets. The book's circular design reflects Tuttle's affinity for the Asian concept of time as a cycle and eternal return of the same, while also demonstrating the currency and reliability of traditional bookbinding through the radical renewal of art.
