I feel I owe a debt to LEGO blocks for forming part of my personality (at least the obsessive, primary-colored, perfected-fitting, perpendicular part). I have always wondered how they made LEGO block (or where they came from for that matter) and how they got them to fit so perfectly together.
I've always been awe of the precision of how LEGO blocks are manufactured, and watching my infant daughter play with LEGO Duplo blocks (the bigger chunky ones), I also wondered how they perfectly adjust the tolerance of when they click together to be just right for kids to find it challenging but not frustrating.
So I couldn't help share this BusinessWeek article on
The Making of a LEGO Brick when I found it.
