On a slow Saturday in Ban Muang Wa village, outside Chiang Mai, Thailand, the hottest action in the village is in the cool shade under the Khuenkaew's house. Three weeks ago, Boontham and Bourphet gave their son Visith, 9, a hand-held video game, and the household has been filled with its beeps and buzzes ever since. The family's dog hangs out with Visith. The Khuenkaew family lives in a wooden 728-square-foot house on stilts, surrounded by rice fields in the Ban Muang Wa village, outside the northern town of Chiang Mai, in Thailand.
