Digital sound design

I took a nice little course on coursera: a (very basic) introduction to digital sound design. Of course, as it goes with such courses, one must create a small composition demonstrating the newly acquired skills (or the lack thereof). I was in the mood for something experimental, so be prepared! Art or Nonsense? Feel free to leave your opinion. Incidently, the piece is dedicated to Patrick De Witte, a journalist and very witty humorist who died unexpectedly yesterday due a "heart failure" (he almost certainly would have seen some humor in this announcement: after all, doesn't everyone die of heart failure?). I didn't know the man personally, but I think he'd have gotten a good laugh out of it.
