Steve Wozniak (aka The Woz), co-founder of Apple computer, has a pretty cool business card. His card is made out of metal and cut using chemical etching and stamping with perfectly precise perforations just like any Apple product. UK firm PlasmaDesign produces these cards in a variety of colors for high-profile clients such as Smirnoff, Bentley, and Ray Ban. The selling point? Presumably, they stand out in the crowd and are less likely to be thrown away.
