Single motor robotic arm

I noticed this amazing device on Brickshelf a few days ago:

So far as I can tell from the pictures and description, it's a pick-and-place
robotic arm, with all the sequencing done mechnically, using a single motor and
no electronics.  Very cool indeed!

It would be great to see more details of how it works, and a video.  But I don't
know any way to contact "shinichiro10".  Any ideas, anyone?
