We had an autistic kid with a photographic memory that joined our school in middle school. They wanted to mainstream him as much as possible (awesome since this was quite a while ago and the only autistic person any of us had heard of). On the first day they gave him a copy of the yearbook and he memorized it right there. He knew every person in the school by their picture, what they did, their class, etc. It was amazing! Sometimes I still run into him and he still knows it all! For him it was a gift as it made him quite popular despite his condition.
