Ann Hamilton is one of my favorite artists. This is one of her older projects from 1999 called Myein which she made for the Venice Biennale. It incorporates both sound and touch (I think also smell). It is at the United States Pavillion where the walls inside are covered with braille text from Charles Reznikoff's Testimony: United States, and there is a voice recording playing which reads Abraham Lincoln's second Inaugural Address in phonetic code. Check it out.
