One and other: Antony Gormley inviting fourth plinth live sculpture volunteers

am really intrigued by this one and other project for volunteers to become a one hour living sculpture in the 'most public space in our land,' in the ideas surrounding 'it is entirely up to you what you do,' spectacle, exhibitionism. shall i volunteer? who will volunteer? what/how/why/what would i do/pose/ wish to literally or sculpturally engage with audience? the expected and the unexpected, the 'portrait of our nation.'
