About a year ago, maybe longer, I was hunting for a unique wedding gift for some designer friends and happened upon Shapeways: a 3-D printing service.  I played around with their online design tools, however opted for a beautiful glass pitcher.  David Minich was shopping for eyewear and used Shapeways to create his own business: Make Eyewear. David creates infinitely customizable eyewear.  The beauty of rapid prototyping is that you can design just about whatever you want, then print it on demand.  What could you make with this type of technology?
