Arundhati Roy didn't want to be pigeon-holed as a pretty authoress with some political views, so she cut her hair off. Picture and recent interview (via Robot Wisdom).

By the way, I checked her Booker Prize winning novel, 'The God of Small Things' out from the library. I read the first chapter and a half and it didn't grab me. I doubt I'll go back to it. I'm not in the mood to persevere. Her writing is self-indulgent, 'precious', though I agree many of her values.
