The octopus, said activist Mark Lipman of Los Angeles, represents Wall Street's stranglehold on political, cultural and social life, with tentacles "that reach into your pocket to get your money and a tentacle to get your house."
Though the Occupy movement is leaderless, it has taken some organization to get ready for Monday's event.
During the rehearsal Thursday, activists were assigned roles, such as working with an Occupy peacekeeping team or carrying the plastic pipes that will support two large replicas of the preamble to the Constitution. Each replica — one with the words "We the People," one with "We the Corporations" — requires dozens of people to hold up. Maneuvering the octopus "human float" took some practice in coordination. Protesters spun in circles, moving it through the park. Each tentacle will have several protesters lifting it.
