Twenty-four hours a day for 100 straight days, different people will join kings and generals high atop London's Trafalgar Square, becoming, if only for an hour, a living monument.

The "One & Other" project, which began July 6, comes from the mind of British sculptor Antony Gormley, who has asked the people of the United Kingdom to occupy the empty Fourth Plinth in Trafalgar Square. (At time of writing, a man is flicking playing cards off of the plinth.)

The Fourth Plinth is the name given to the empty plinth in the square. Built in 1841 to display an equestrian statue, there were not enough funds available at the time to create a statue.

"Through elevation onto the plinth, and removal from the common ground, the body becomes a metaphor, a symbol," Gormley says. "In the context of Trafalgar Square with its military, valedictory and male historical statues to specific individuals, this elevation of everyday life to the position formerly occupied by monumental art allows us to reflect on the diversity, vulnerability and particularity of the individual in contemporary society. It could be tragic but it could also be funny."

(Man on plinth is now looking bored, raising his arms triumphantly for no apparent reason.)

The rules for participants are simple: Stand alone for the whole hour, do anything you want but don't break any laws and take anything with you that you can carry, which being London should probably include an umbrella.

Can't make it to London before the final hour on Oct. 14? You can watch every hour and all 2,400 participants on this live Web cam. (Man is now sitting and eating a snack.)
