Kiwi master craftsman Sören Berger is a woodturner, teacher, and inventor with 35 years at the lathe. It shows. In this amazing and slightly terrifying video, you’ll see him turn a giant tree trunk section that starts with the bark still on it, inside and out, until it’s perfectly smooth and translucent-thin. Inspiring and wonderful. Absolutely do not miss it. [via nerdstink]
