A very sad exhibition. That kind of art doesn't add something in our life . They put a tremendous efforts to create something new and end up with emptiness . That's why they offer for free anything you see inside the exhibition. They better look more inside themselves because they lose the essence of life.
I cannot quite agree with you. The pieces that they are giving out are not intended to bring any physical value for the viewers are probably wouldn't attract anyone who's just looking for free stuff (well, the t-shirt was probable the most valuable thing there). Every artwork has an idea behind that and a reason why an artist wants you to own a part of it. While I'm not a big fan of conceptual arts, there were still some works that I believe are really interesting and leave you food for thoughts
