BusinessWeek has a big story today on 3-D printers and how great they are. Of course, we all are way ahead of them, having already examined the dream projects of 3-D printing's brightest stars, among lots of other things. What we didn't know was that 3-D printers could be used as a (totally legal!) supply shop for street toughs like these teenage ruffians in the back alleys of Santa Clara, CA.
From the article: "'I will stab you with flash drives,' Riley tells Vernon, a skinny boy with a braided rattail who shows off a pair of freshly made plastic brass knuckles."
It's like West Side Story, but with future engineers instead of future dancers.
