The late-1960s and 1970s also witnessed the appearance of "Body Art", a type of Performance in which the artist's own flesh becomes the canvas and subsequently "performs" in a suitably shocking, newsworthy manner (for more see below).During the 1980s, Performance art increasingly relied on technology (video, computers) to deliver its "artistic" message.Important exponents of Conceptualism include Sol Le Witt, Joseph Beuys, Felix Gonzales-Torres, Eva Hesse, Jenny Holzer, Joseph Kosuth, Barbara Kruger, Jean Tinguely and Lawrence Weiner.
Moreover its insistence on being labelled "art" - traditionally a bourgeois event - sits awkwardly alongside its anti-establishment ethic.
Performance now includes events and "happenings" by visual artists, poets, musicians, film makers, video artists and so on.
A good example is the series of self-destructive machines - probably the most famous examples of kinetic art - created by the Swiss artist Jean Tinguely (1925-91).

Fluxus was an avant-garde group of artists (its name means "flowing" in Latin) led by the Lithuanian-born art theorist George Maciunas (1931-78), which first appeared in Germany before spreading to other European capitals and then New York City, which became the centre of its activities.
