Bicycle for 6?

On the weekend i saw this creation being ridden (or driven?) around. It operates like two bikes joined together, with each half being a 3-person version of a tandem bike. The front person has a steering wheel instead of handlebars.


Shortly after this photo was taken i saw it carry 9 people (though only 6 could pedal). I'm not sure that i'm really advocating this as a major form of transport - can't really think of that many applications for it. But the creativity certainly caught the eye - and the imagination.
