Starting at 11:00AM this morning, LACMA is holding a marathon screening of their newly acquired work The Clock, conceived by American artist Christian Marclay. The Clock is a 24-hour movie and art piece that strings together moments from cinema and television that feature clocks and watches. The most impressive part of the work is that the images are chronologically synched with the actual time of day, so if you were to look at the film at 6:04PM tonight, you would see an image from film or TV where a clock shows the time at 6:04.

The museum is keeping their Bing Theater open throughout the night until the film ends at exactly 11:00AM tomorrow, so you still have plenty of time to check it out, and admission to view the piece is free, courtesy of KCRW. You can also follow LACMA on Twitter for updates about the exhibition. In case you miss it, the piece will be available to view during regular museum hours starting on Friday through July 31st, though it is not scheduled to show in its entirety any time soon, which means today is your only shot to see the parts of the film that occur during their normal closing hours.

The museum acquired The Clock in mid-April after the work enjoyed a fantastic reception at the Paula Cooper Gallery in New York and London’s Hayward Gallery.
