This is one of many short video segments which will be added to the Digital Tipping Point (DTP) archive.  This series of two video segments features Jin Sato, a research scientist with the Advanced Industrial Science and Technology Institute of Japan. It has been said of Jin, and rightly so, that you can’t help but smile after being in Jin's presence for only 5 minutes. So check yourself, because I bet that within three minutes of watching Jin's video, you too will be smiling. It's just infectious with Jin.
