ありがとう、Hair Station LEON
I was sleepily goofing off on Skype tonight (or this morning... about 2am), when I came across a guy in Nagoya, Japan working in his salon, Hair Station LEON, which is apparently famous for their shampoo robot! They have a live webcam at their site, and actually posed for me so I could post the screen capture here.
I still say the Internet is a wonderful thing. Most of the time.
