I ran across this page about minimalism. The current post are prints on the sea, but the blog is about minimalist film, music, literature, poetry, architecture, and art. Dirt :: A Journal of Minimalism is another blog that has self proclaimed minimalist poetry. If you want more info on minimalism go to minimalism.net.
Some visual artists that are minimalist: Agnes Martin, Barnett Newman, Ad Reinhardt, Anne Truitt, Ellsworth Kelly, Donald Judd, Sol LeWitt, Jo Baer, Carl Andre, Frank Stella, Robert Mangold, and Richard Serra.
