Shaka: A Story of Aloha: A documentary on the origin, meanings and uses of the gesture. The shaka sign is reputed to be over a century old, but its origins are the stuff of myths and legends. It turns out that kupuna (Hawaiian elders) have kept the story secret for almost a century. Why? They didn't want it told incorrectly or commercialized. But given advancing age and a world in need, they decided it was time to share the story.
