Borneo-lightning flashes across the dense forest, and buckets of rain wash away the day's heaviness. Night falls on this Dayak village, perched on a hill above the Kayan River.

Inside the home of the leader of the village, two dozen people sit down on the concrete floor for an evening meal. Once a week, these subsistence farmers gather for food, conversation and a few cups of rice wine. They usually eat by candlelight, because their village lacks electricity. It does not, however, lack innovators.
