This is part of a series of post on Visual Poetry that Geof Huth did for the Poetry Foundation. Here's an excerpt about Gustave Morin's fun example of VisPo:
Gustave Morin's primary form is the collage poem. His "toon tune" is a
remarkable piece of craftsmanship. Its sixty-three individual fragments
of text are cut into the shapes of jigsaw puzzle pieces and are fit
perfectly together in a rectangular grid. The "words" of the poem
consist almost entirely of the extravagant visualizations of
onomatopoeia from comic books, producing a visual symphony of crashes
and cries.—Geof Huth
