The key section of the source code, for me, was not an algorithm or subroutine but rather the dedication on line 1, which glues the pieces of his collage into an emotional whole.
I have a friend who regularly reads the online version of Pravda and manages to widen his point of view. I'm stuck in a rut reading the NYTimes each day. A piece like yours reminds me that I could read any point of view at all on a given day -- from South Africa, Pakistan, China, etc. But my mind is the block to doing so -- realizing that it's possible. Your piece is that reminder. The 3 layers are also well used -- by using newspaper sites, I'm reminded of printing offset and overprint errors. The rhythm of the code is nice and simple - like 3 chords :
absolute; left: 0px
absolute; left: 200px
absolute; left: 400px
The most cryptic language, at least to me, is Perl. As in Martin's piece, it's astonishing what can be accomplished with so little, and the few Perl scripts that I have written have indeed impressed me with how few lines you need to get the job done. Sawad shows this most effectively with his contribution, making a complete collider in a few dozen lines.
The orderliness of Sawad's tapestry was a real surprise for me. I'd seen other collages of shredded news -- I'm thinking of Burroughs' mid-century experiments, and Napier's well-known piece -- and hadn't realized how malleable the news-substance could be, or how clearly it could reveal the artist's hand, until now.
