How can animation enhance poetry?

Just a few thoughts on creating poetry animations:

What kind of animation works for poetry? - in fact is there a 'kind' of poetry animation? Are there underlying trends? I have seen a lot of poetry animations where someone had animated an existing poem. What about starting the other way round? I'd like to see examples of this. Or where they are created together - like a piece of devised theatre.

If you do start with the poem, do the images  represent or complement the words of a poem? How can animation help to unpick layers of the poem rather than just illustrate it?

I see a lot of similarities between animation and poetry: the tightness of the media - being able to say something in a short honed piece. The use of metamorphosis and transitions in animation lends itself to poetry very well. They can both go anywhere. Poetry's use of metaphor, symbols, rhythm etc can be explored beautifully in animation. But I do think that there has to be something that the animation adds to the poem, rather than just being an illustration.
