In the early 1980s, Marc van den Broek focused largely on spatial installations based on a symbiosis of art and technology: the flying objects known as mutants.
[1] The Declaration of Independence (Die Unabhängigkeitserklärung) was realized between 1990 and 1992 as a kinetic sculpture which marks the end of the era of materialism in the waning years of the industrial age.
Inspired by intensive, long-term cooperation with leading industrial and commercial firms, Marc van den Broek developed the project entitled "The Impact of Art in Business."
In this work he takes up Joseph Beuys's concept of "Social Sculpture" and concludes that the symbiosis of art and entrepreneurship is a synergetic process of creation which contributes to the spiritual development of society through innovation and revelation.
Marc van den Broek continued to pursue this approach during his years in New York (1998–2008), where he worked with numerous well-known companies.
