Yoko Ono Organizing Giant Human Peace Sign to Mark Lennon's Birthday

"You don't have to do much. Power works in mysterious ways Visualize the domino effect And just start thinking PEACE," said Lennon's widow in a Twitter post that has been circulating on different social networks for the past few days.

The event will be held on Oct. 6 on Central Park's East Meadow, where Ono hopes to assemble up to 10,000 people to pay homage to Lennon, who would have turned 75 on Oct. 9.

Participation in the event is voluntary, but organizers have set up a Web page where they will accept donations by fans of the former Beatle to be forwarded to the Imagine Peace organization.

"Thoughts are infectious. Send it out. It's Time for Action. The Action is PEACE," said Ono on another message sent to her more than 4.7 million followers on Twitter.

Lennon was shot to death by a lone gunman on Dec. 8, 1980, on the sidewalk outside his residence in the Dakota apartment building on the other side of Central Park, where the Strawberry Fields garden was established to pay tribute to him.
