Production I.G. (from Ghost in the Shell, Pat Labor, Evangelion, the Kill Bill animation etc) did a collaboration where they (re-?) designed a Nissan and used it in their animation series Stand Alone Complex.
The interesting thing is that nissan decided to built a prototype of the concept car and has it on show in their gallery. I personally really don't find the car amazing at all, if not to say dissapointing. Still interesting when something like this happens though.
Please let somebody make and put in production Syd Mead's flying cars from Blade Runner (Even if it doesnt fly...).
In Japanese but you can still check out the ride
the nissan gallery for the peeps in Japan
