Adam Kirsch in Harvard Magazine:
The most notorious and beloved child in modern American poetry is E.E. Cummings. Even readers who seldom read poetry recognize the distinctive shape that a Cummings poem makes on the page: the blizzard of punctuation, the words running together or suddenly breaking part, the type spilling like a liquid from one line to the next:

Cummings was not the first poet to use a typewriter, but as this poem shows, he was the first to take advantage of its power to control the exact spacing and shape of every line, and thus to make a poem’s visual appearance as important as its musical rhythms. What looks like a thin trickle of letters becomes, to a reader who has learned Cummings’s tricks, a picture in print: the snowflake “alighting” in a twirl, the severe vertical of the “gravestone.” This playful tinkering with language is the most obvious and appealing sign of Cummings’s originality; as he once wrote, it is “such minutiae as commas and small i’s,in which…my Firstness thrives.”
