"The Oyez Project is a multimedia archive devoted to the Supreme Court of the United States and its work. It aims to be a complete and authoritative source for all audio recorded in the Court since the installation of a recording system in October 1955. The Project also provides authoritative information on all justices and offers a virtual reality 'tour' of portions of the Supreme Court building, including the chambers of some of the justices."
