I should have had Jim Andrew's Vispo site in my links long ago. his work is seriously playful, and he is one of the most eloquent thinkers on the subject of visual... well, I was going to say visual poetry, but Jim's work inflects more particularly towards the internet whereas visual poetry conjures the work of, say, Geof Huth, who is indeed an eloquent champion of that vocabulary. if you want to get caught up in terminology. I like this integration of theory into the artistic act. Grenier has this same integration. his visual work extends from his poetry, his poetry from his theoretical work. totally ambient.
