Koko the signing gorilla
Crippled Monkey, being a monkey, was particularly excited to hear about this website (keep up with the pretence).
Koko's World learns you how to speak sign language. Only it's not BSL (British Sign Language), it's ASL, American. And it's not proper ASL either, it's gorilla ASL. Yeah, the kind of ASL that arch chimp President Bush might be learning later in life.
Oh, are you loving the freedom of speech in the Western world? Well, learn some more with Koko, then pop down to the zoo and have a chat with an ape. Deaf or hearing.
The great thing here is that if you are not a sign language user, after going to this website you'll be able to tap into any deep and meaningfuls that deaf zoo-goers might be having with the exhibits. Possibly.
