There's an unintentional personal joke in there for Mirror, but it's an interesting discussion.
"Art is a man's name," as Warhol allegedly said.
As I said in my comments, "but I like Duchamp" and I don't like Rothko, and I'm not so fond of Pollack, but I'm way ahead of my mother who can only appreciate representational art. Is this artist, Martin Creed, laughing all the way to the bank (as my parents used to say), or is he on to something. He does seem to have an odd vision of all the canvases and statues stacked up and taking up space.
Theater art for instance is about both what is there and what isn't there. Negative space to use the general term, which can mean both the white or empty space on a canvas, or the literal empty space on stage where there are n actors or set. This is then the ultimate piece of negative space with no "positive space" to surround it or define it.
