I've seen some quite good examples of this in some things I've read. A poem I know was written incorrectly in order to force people to read it in a particular accent[1]. Also, "Feersum Endjin" by Iain M Banks has some chapters written from the perspective of one of main characters written in non-standard English[2].

Then of course there are the classics such as Trainspotting.

the role of language in shaping our experience is a HUGE element of the story. i guess i read too much snow crash.

Having also read Snow Crash, I think you're extrapolating a little too far. The composition of words shapes experience, not small syntax choices.

Plus, I don't know that it's a huge element of a story (I can't tell if "of the story" means your story specifically or all stories). The culture shapes language, and the culture shapes the story. The language's influence on the story isn't anywhere near the culture's.
