At work, so I am skipping the vid. Looking at the ad, I wonder if I would have played with Lego (or Duplo, the toddler version) more if there had been sets all in one color available at the time. (They're available *now*, but not in upstate NY in the mid-eighties. Internet, ILU.) I seem to remember making something and getting really frustrated that there weren't enough bricks in the right color to finish whatever I was making.
