If I'm going to do something a little bit more adult, I'll do it if it's going to be on at a different time slot or if it's going to be something that kids won't be able to get their hands on.
I think that concrete poetry seems to have, as far as I can see, come to a kind of a dead end. It doesn't seem to be going any further than it went in its high period of about five or six years ago.
