Flying cars are of course set to become a reality in the relatively near future, but we doubt the first operational models will be as cool as the Audi Shark. A cross between a motorcycle and a plane, the design concept by Turkish creative Kazim Doku won the 2009 World Auto Design Contest.
Another jaw-dropping tub concept, Bathingsphere by the Alexander Zhukovsky Design Studio in Russia is a glass ball tub suspended from the ceiling.

The ultimate doghouse, this luxe pooch pad comes complete with a treadmill, automatic feeder and hydrotherapy bath. The two-room kennel did actually make it past the drawing board, but Samsung only manufactured a single model, which was given away as first prize in a 2015 Twitter competition. You never know what the future holds, though.
