I was first introduced to Haikus in some Perl related webpages, and to be honest, Perl is the first language in which I see (the try of) poetry at all. :)

Personally I'm attracted to Haikus, because they are so short that one must focus on the essential thing, much like an 16x16 (or 32x32) icon forces me to focus on the essence in the thing I try to portray. I also program(med) some really small programs (programs that do amazing things in under 50 bytes of x86 code), so I guess that at least in my case, small is beautiful.
