    Scientific American Presents the 2012 Consumer Electronics Show (CES) [Slide Show]

    Ultrabooks, smart phones and gadget-friendly automobiles were the stars of last week's International Consumer Electronics Show (CES) in Las Vegas. But they were hardly the expo's only bright spots. Spread out on a show floor more than 37 football fields in area were plenty of robots, 3-D printers and a variety of new gadgets.

    I prowled the floor and came away with photos sampling some of the sleekest, most interesting—not to mention bizarre—technology I could find. Some of the most striking were prototype concept cars that will probably never be used for passenger drives, such as an electric-powered re-imagining of Doc Brown's DeLorean DMC-12 from Back to the Future as well as gorgeous gadgets like Alljack's $68,000 gem-laden wireless speakers.

    Click here for a slide show of this year's CES.
