I say "sunburst". Definitely. Nice examples shown, but great in other locations than just over a bed, too.
I love them, I have referred to them as both actually. They are just beautiful, I just helped a good friend select one for her bedroom....they are beautiful accents.
I usually call them suburst :) We have some great ones, if you'd like to take a look!AJhttp://www.jeanmarcfray.com/
