Suddenly, Lexus' hoverboard doesn't seem quite so impressive. The automaker has unveiled the Origami Car, a fully functional electric IS sedan whose main body, interior and wheels (!) are made out of cardboard. The designers laser-cut 1,700 pieces based on the digital model of the regular car, and stuck them all together using wood glue -- that's not exactly a quick process (it took 3 months to put everything together), but this would have been virtually inconceivable in previous decades. You're not going to see this vehicle on the streets, of course. The instrument cluster is nothing more than a bunch of drawings, and cardboard simply isn't going to be comfortable or safe. However, the Origami Car is proof that modern assembly techniques can build just about everything out of seemingly anything.
