In that case, could you please name a few artists that you believe did exactly that? I'm honestly interested in finding more of such art. But before you do, let me rephrase what I wrote above, because it's easy to misunderstand one short sentence (and I'm definitely guilty of not explaining very well what I mean): When I talk about art around and about software, I mean
a) art, i.e. not just something beautiful or well-crafted, but something which explores the human condition with an artistic purpose
b) around software, i.e. art that uses code as an integral part of the artwork (not just a painting about programming for example)
c) about software, i.e. it does not only use code to convey something, but code itself is the subject (Code for Code's sake)
I'm honestly not aware of anything that fits this description before _why's work (or at least of nothing that I would consider as art, and yes, that's somewhat hard to define). More concretely, I would exclude any works that simply praise mathematical / structural elegance, perfection or purity. Even though their creators may be artists and use artistic methods, I would hesitate to call such works "Art" with a capital A.
So, games/demos/processing sketches/audi-visual programming/software patterns/etc all do not fit these criteria. They may be very skillful works of art, but none of them tackle the subject of software & code at their core. While many focus on the mathematical perfection in code, _why focused on human imperfection and a creator's struggle while writing code.
