TED2010: Ten fascinating people you've never heard of:

Temple Grandin, autistic professor

Temple Grandin sees her autism as a gift, not a disability. The professor at Colorado State University, who has become a prominent animal rights activist, spoke at TED about how people's brains work in different ways -- and how that's something that should be appreciated, not stigmatized. Grandin, for instance, thinks in pictures, "like Google for images," she said.

She also grabs hold of details, a brain function she feels could help politicians.

"I get satisfaction out of seeing stuff that makes real change in the real world," she said. "We need a lot more of that and a lot less abstract stuff." One of her biggest real-world accomplishments, she said, was that a mother recently told her that her autistic child had gone to college because of Grandin's inspiration.

Grandin's life also is the subject of an HBO film.
