Monowheel that doesn't work

The following is a series of photos of a "Monowheel" contraption which doesn't actually work and was designed by British designer Ben Wilson. Its apparently not very comfortable either.

The concept isn't new and there are working versions out there built by different people, but no one has managed to design one which works "properly" despite many inventors who have tried. There have been motorized versions made also, but likewise there are always design faults.

Still, its amusing.
