Christian Marclay’s 24 hour video installation ‘The Clock’ – praised as one of the standout artworks of the past decade – opened today at Lincoln Center as part of the Lincoln Center Festival. Composed of thousands of film clips featuring timepieces, and synched with real time, it entertains while making viewers eerily aware of the time they’re spending watching it. Arrive early – lines snaked down the block to view it in Feb ’11, so check out the Festival’s twitter ‘line update.’ Watch a few minutes of ‘The Clock’ here. (Runs through Aug 1st).
