I found it weird that they're also contemplating sign-language translation of the artists' <i>gestures</i>. Why is that needed? Are generic gestures made by hearing people in a different "language" from what deaf people would use?<p>Or is it the other way around, that since deaf people have a full language available using (intricate) gestures, they don't "need" (and therefore never learn) the more generic gestures used by hearing?
