[1] From 1995–97, the Mattes toured major museums in Europe and the United States, and stole 50 fragments from well-known works by artists such as Duchamp, Kandinsky, Beuys, and Rauschenberg.

[5] In addition, they have orchestrated several unpredictable mass performances, staged outside art spaces, and involved unwitting audiences in scenarios that mingle truth and falsehood to the point of being indistinguishable.

They define this in an interview with Jaka Zelenznikar where they discuss audiences reaching a website, regardless of it being the subject of net.art or not, and "by their mouse clicks they choose one of the routes fixed by the author(s), they only decide what to see before and what after".

When displayed in a gallery setting the monitor is positioned on its side with the reaction playing on the top half while the bottom section remains black.

The work is also set up to face away from the gallery's entrance in order to enable new visitors to first see the reactions of the live audience before watching the ones on the screen.

The Mattes shocked the mainstream art world with the invention of "Darko Maver",[17] a reclusive radical artist, who achieved cult status and was paid tribute to in the 48th Venice Biennale, before being exposed as pure fiction.

[18] The fiction was that this Serbian artist created very gruesome and realistic models of murder victims and positioned them so to obtain media attention.

In fact, they stated that anyone who claims that their work is an original, should really "start doubting" their mental health, because practically everything in this world, not just art, is a reproduction or remix of something that has been released before.

[21] The, now destroyed, portrait has become a new work, 'Killing Zoe', another edition to their attempts to debunk originality; this has only become something new due it being a part of a new event, all the subject matter is the same but it comes in a new form.

Riccardo was chosen by the artists from a social media notice in which the Mattes offered $1,000 to anyone willing to give full access to the photos and videos in their phone to be turned into art.
