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
