This is such a cool thing!
I saw one of these machines for the first time at Rimsky's in Portland this weekend. You put in a quarter, you get a gumball and a piece of paper with a poem on it. Actually, I got a Mike and Ike instead of a gumball... but I don't care.
You can find these machines in a few different places in the western states, but mostly in Portland. If you don't want to buy gumballs with each individual poem on them, you can read the entire issue on their website. Its located at www.gumballpoetry.com.
