Yoko Ono is organizing the world's largest human peace sign to celebrate what would have been John Lennon's 75th birthday on October 9.

Ono hit Twitter to ask for help in making the Guiness World Record.

"You don't have to do much. Power works in mysterious ways. Visualize the domino effect. And just start thinking PEACE," wrote Ono.

She added, "Thoughts are infectious. Send it out. It's time for action. The action is PEACE."

To participate is free, but Ono is accepting donations to go toward the John Lennon Educational Tour Bus, a non-profit mobile audio and video recording facility for kids.

Ono plans on capturing the human peace sign with aerial photography.
