Transparency in manufacturing is fascinating – being able to peer inside the LEGO factory or watching how TCHO chocolate is made really gives you a feel for the product that you wouldn’t otherwise have. But transparency can also be selective: what about a photogenic cigarette factory or Nike’s pride about their only non-sweatshop shoes? Then again, there’s outright lies: that’s what fascinates me about Youtube user How Things are Made, with fascinating videos on the manufacturing of steering wheels (above) and this amazing insight into the compact disc manufacturing process (below). Watching manufacturing processes is deeply satisfying, no matter how real.
