I have always wanted to learn sign language, and my labmate, who is an interpreter, recently began teaching me American Sign Language. It's been very fun to finally be learning it, and a great education in non-verbal languages (which I'm obviously interested in!).
She also recently sent me a link to That Deaf Guy, a comic about a deaf man and his family. It's a very smart and well done strip, that has some great humor about signing and deaf culture. My favorite are the "Dos and Don'ts" of relating with deaf people. Go check it out!
And, along those lines... here's an awesome deaf rapper!
