If you're not convinced of the S.Y. - Noguchi link then take a look at this version of the standard S.Y. Robot with Spark. It's been given the spinning antenna treatment and released in a box with the N logo. This is a rarer variation of the common flapping-foot robot. The box is particularly attractive, and very hard to find. S.Y released the same variation in virtually the same box, but it's called Mechanical Walking Robot.
