I don't see much difference between prose poems and flash fiction (I've often taught the latter as the former), but then I also don't see that much difference between art and poetry.
Matthea HarveyI am charmed by concrete poetry (but it's very hard to do well, I think) and in general by the idea of mixing the visual and the textual.
