The flowing symbol resembles three figures - orange, green and blue - embraced at the arms and in a flowing dance.
“The logo for Rio’s 2016 Games conveys passion and transformation.
The passion of all Cariocas and Brazilians for sport and celebration,” said Carlos Nuzman, president of the Rio Olympic organising committee, “Carioca” being the name for Rio’s citizens.
“And the transformation that the Games are already bringing to Rio and to Brazil.”
A giant TV screen set-up on Copacabana beamed the logo to cheering spectators.
