http://videosift.com/video/Tribe-Meets-White-Man-for-the-First-Time Very interesting, from documentary filkmaker Jean-Pierre Dutilleux shows the Toulambi tribe in Papua New Guinea.  The music is Sacred Spirit – Yeha Noha.  He shows them matches, mirrors and other wondrous new things.  I like at the 7 minute mark when the tribesman takes the mirror and covers it with a leaf so he can sneak up on it.  At 9 minutes they are tasting what looks like a white rice, and the taster signals the tribe by hitting the side of his head.  That’s clearly a signal that makes them all want to taste it.  Then he sprinkles what might be salt and gets a big reaction.  Near the end he wows them with a voice recorder.
