Description Is that a bird? Is it a plane? No, it's a poem! Concrete poems are shaped like their subjects. They can look like objects, animals, or even people. You won't find many straight lines here! Award-winning author Brian P. Cleary explains how concrete poems work, and uses them to create all sorts of wild wordplay. Ode to a Commode is packed with mind-bending poems to make you puzzle and ponder. And when you've finished reading, you can try your hand at writing your own concrete poems!
