This is an example of grassroots innovation, jugaad is the Hindi word for it (http://en.wikipedia.org/wiki/Jugaad). Countless millions are spent each year on "how to foster innovation" etc., most of which is BS. As seen here it only takes a hacker that doesn't know that what everyone else believes, i.e. what s/he is building is impossible/very hard.

EDIT: Most comments here are missing the main point, he doesn't care if the center of gravity is high or if the thing is pretty much uncontrollable or that you can't mass produce these or that it has been done before. He just BUILT IT and as far as his goals are concerned he is extremely successful, i.e. the thing gets off the ground. That, to me, is the quintessential hacker spirit.
