Luciana Tamas: isn't there the risk that only a quite elitistic zone to be able to perceive a such message.

I understand the question. You write: "isn't there the danger for that "hybrid" which results from their combination to not be intercepted with enough clarity by those who watch each one of these domains in a traditional way ?
It is obvious that the poetic metaphor can find its correspondent in form, as well as the visual image (even the one generated by computersystems) has, certainly, a metaphoric component, but this implies also a receiver with an extremely well-trained vision. The question is: isn't there the risk that only a quite elitistic zone to be able to perceive a such message". .

Who do we make the art for? Is it the public or does the artist just want to present his message in the timeframe and possibilities he is offered? In Mail-Art the art goes originally from artist to artist. No gallery needed. What I send goes direct to the observer and he/she should be able to interpret what I send him. if not, than the message is lost (or maybe archived). The observer doesn't have to be well-trained. I made the piece especially for him/her. Also there is normally no money involved. The artworks are gifts from one artist to another. So the concept we are dealing with in mail-art is completely different from the artworld. It is actually avoiding the official artworld. That sometimes work does end up in museums is just because they catch up and want the new markets too.....
