I've found another new form that I would like to try this week. It's called hay(na)ku and was created in 2003 by poet Eileen Tabios. Here are the guidelines.
Hay(na)ku is a 3-line poem of six words with one word in the first line, two words in the second, and three in the third. There are no other rules and no restrictions on number of syllables or rhyme.
You can learn more about the form at Poetry Form. I love this example posted there.
Love isn't math.

Need some examples? You can find some at the Hay(na)ku Poetry blog. (Look for the Hay(na)ku contest winners.) There is also a thoughtful essay about the form at Dragoncave.
As you'll see from the examples, some folks create poems comprised of several hay(na)ku strung together. So, what kind of hay(na)ku will you write?
