To be perfectly honest, I find this much more interesting and artistic than a lot of modern "art."
For example, I believe these Blobs of Glass are little more than interesting candy dishes (not $20,000+ works of art).
The black cube satisfies a lot of requirements for great art, in my mind.
1) It's different. I haven't seen anything like this before.
2) It is a one-of-a-kind. The market really can't support more than one of these.
3) It generates interest all by itself. (Any market it creates is all self-generated buzz. Most other art is only successful because of heavy marketing campaigns and artist self promotion).
4) It says something about our current society (There are a lot of ways you can interpret this piece).
5) It is a shared experience.
Compare it to the candy dish blobs. They look a lot like things you can buy at Wallymart. There's thousands of them. The artist is mostly successful because of heavy marketing. There's no real interpretations besides "Wow, psychedelic man!" I'm unsure that anyone discusses the artistic genius of the glass-blobs, so I don't feel they qualify as a shared experience.
