I recently saw this cool book which I bought called "Poke in the I" which is a collection of *concrete* poems.  What's that supposed to mean?  Well it means that the poems are not only about what they say but how they are laid out on the page.  Below are some examples

Here's one called "Tennis Anyone?" by Monica Kulling

Here's another called "Popsicle" by Joan Bransfield Graham

Anyway, if you find them cool then get the book 😉
