That's what I going for. I tagged it as "Code as Art." I initially dubbed it a poem but decided it read more like a letter, instead. Personally, I think it qualifies as code prose.
Don't take me wrong, but I do not think that this poem (or, as @jpfuentes states correctly, prose) can be categorized as "art". I think of it as a lovely crafted letter, written on a very unusual support. Nothing too much different from a cross-stitched handkerchief.
