It's true. There's a display like that at the Pompidou Center, as well.
Now... let me just say, that I don't think that the contents of the garbage can are visually pleasing or took a lot of effort for the "artist" to arrange (or dump) in the acrylic box. However, if you think of art as a way of examining mankind, the human condition, or as a slice of everyday life (you may... you may not... I'm not going to tell you what art is or isn't), then I can see the value in it. But to me, if it's going to be labeled as art, then there should at least be some kind of commentary along with it. You know, if there's going to be three Coke cans, a subway ticket, and a half-eaten sandwich on display, then maybe use those items to address branding (since Coke is a universally recognizable brand), or how a subway ticket identifies the garbage as coming from a certain place, and therefore makes the rest of it that much more interesting (maybe).
Anyway, I'm not necessarily trying to defend "garbage can" art to anyone. I think I'm more trying to understand what purpose, if any, there is in displaying it.
HOWEVER, that is not really my style of Modern Art. So when I say I love modern art, please don't let that be the thing that jumps to mind. Instead, why don't you think of these?
Wind by Xao Wou-Ki (I love how moody this canvas feels, even without knowing the title).
Untitled XX by William de Kooning (I just love the riot of color and that there seems to be no rhyme or reason to it).
Detail of a painting by Simon Hantai. He folded the canvas a bunch of times until it was small, then only painted the surfaces that showed. Unfolded it, refolded it, applied more paint. After many times of doing this, the resulting canvas is randomly covered in color (possibly more than one) or even left completely blank in places. He did have a purpose in doing this (something to do with ignoring the will of the artist in the placement of paint, letting it just be random, etc.), but I just really like the overall effect.
Oh, Mark Rothko. I think your paintings are wonderful. Deceptively simple-looking little festivals of color.
Love me some Jackson Pollock. This is a detail of 'The Deep.'
Nicolas de Staehl's "Les Toits." I absolutely LOVE this painting. It's quickly becoming a new favorite. I'm kind of traumatized by the fact that he killed himself after meeting with a particularly harsh art critic. I hope I get to meet him in heaven and tell him how much I love this painting. (Is that weird? Maybe just a little, but I would totally say the same thing about Monet, Van Gogh, Pollock, Rothko, and many others.)
Kupka's "Autour d'un Point" (..."Surrounding a Point/Dot" maybe?). Very graphic. Very cool.
Kupka's "Animated Lines" and Delaunay's "Rythm with no end"
Jasper Johns - Figure Number 5
More Simon Hantai. This is titled 'Painting' and called "Pink Writing." You can see there are a couple of different things going on with splotches of color and the dripping black circles...
but what you may not realize at first is that all of the texture and detail covering the whole canvas coms from handwriting on the canvas. Hantai wrote directly onto the canvas (I think it took the better part of a year or more) in pen. If I remember right, he copied down famous quotations or inspiring passages of literature or other texts. He made himself write on the canvas for an hour every day or something to that effect, until it was complete. I would never put myself through that, but he seems to be the very dedicated, experimental type who is willing to put in a lot of time to see the results of a certain approach (c.f. the folding canvas experiment noted above).
