Mario Kart Wii is on the way this month. Everyone by now is familiar with the plastic wheel attachment that is being packaged along with everyone's favorite kart racing game. Did it ever occur to you how hard it was for Nintendo to create that little add on?

You know perfect racing wheel attachments don't grow on trees right? Nintendo being the innovators they are, decided the wheel design that has been around since the dawn of man was not good enough for Mario Kart fans.

2 years of work & nearly 30 prototypes later they successfully find a suitable wheel. Check out the whole process at Wii.com.
