Great talk from Ignite Seattle by Ken Beegle has some great overview of Polynesian navigation techniques. The talk is really has a deeper meaning, but he does a good job in his allotted 5 minutes covering the stick charts.

Ignite talks are timed 5 minute min-lectures, the slides are pre-programmed to flip automatically and the presenters have to have it down-pat. My friend Brady from O’reilly publishing hosts these in Seattle and they occur around the world.
