Young-Hae Chang Heavy Industries (Young-Hae Chang, Marc Voge)

Young-Hae Chang Heavy Industries (장영혜중공업) is a Seoul-based Web art group consisting of Young-Hae Chang and Marc Voge. The group formed in 1999. Young-hae Chang is a Korean artist and translator with a Ph.D. in aesthetics from the Universite de Paris I, while Marc Voge is an American poet who lives in Seoul.

Their work, presented in 20 languages, is characterized by text-based animation composed in Adobe Flash that is highly synchronized to a musical score that is often original and typically jazz. In 2000, YHCHI's work was recognized by the San Francisco Museum of Modern Art for its contribution to online art. The group uses "Monaco" as the font for all their work because they liked the way the name sounded. In 2001, the group was awarded a grant from the Foundation for Contemporary Arts Grants to Artists. Their solo show, "Black on White, Gray Ascending", a seven-channel installation, was part of the inaugural opening of the New Museum of Contemporary Art, New York, in 2007. They are 2012 Rockefeller Foundation Bellagio Creative Arts Fellows. In 2018-19 their work was part of the 9th Asia Pacific Triennial of Contemporary Art (APT9) at the Queensland Art Gallery/Gallery of Modern Art, Brisbane, Australia.

According to the artists, their piece, Dakota, "is based on a close reading of Ezra Pound's Cantos I and the first part of II." Their pieces are characterized by speed, references to film, concrete poetry, etc. Their work is sometimes called digital literature or net art, but there is no consensus.

Their work is held in the collections of the Tate Museum, the Centre Pompidou, Paris, Queensland Art Gallery | Gallery of Modern Art, Brisbane, Australia and M+ Hong Kong.
