In his workshop in Hakone, Japan, a master craftsman shows us the art of Yosegi-zaiku. You really should watch the video before you read the Wikipedia article on it, because you'll enjoy discovering what it's all about as he goes through the process.
Also, the video itself is beautiful and soothing, with lovely music. If you spot any finished Yosegi-zaiku products in a shop, or maybe in a friend’s home, you’ll be glad you can explain what goes into it. -via reddit
