This is a metaphorical image. I believe there's no such thing as a perfect (human) family. In order to use the phrase "perfect family" I would have to be talking about something synthetic like a family of cars, products... or robots. Even then, this synthetic family would probably not be perfect.

I modeled the robot in about 10 hours and it took nearly the same time to render at print resolution (16x6.5"). Initially I wanted to design three distinct robots to portray a father, mother, and child figure but since I was on a tight schedule I simply adjusted proportions to arrive at this design.
