Analogy Poetry

This kind of poetry sounds like its going to be a challenge. Analogy poetry is relating two or more things in a poem that are otherwise unalike. Like relating a balloon and a horse. They have nothing in common but you could relate riding a horse to being lifted away by a balloon. A good poem to read is Nothing Gold Can Stay by Robert Frost. Anyhow, I like the style, the only trouble I can see is trying to write them. Lets hope they turn out alright!
