CES 2012, known officially as the 2012 International CES, is the largest tech show in the U.S. and a spectacle that has to be seen to be believed. First of all, CES is massive, with exhibit space that covers more than 35 American football fields. Not impressed? Well, try this: CES is held in Las Vegas, easily one of the world's most bizarre -- and therefore fascinating -- cities.
CES also attracts attendees from countries all over the world -- as can be surmised from the olfactory onslaught of attendees' colognes and perfumes on encounters while strolling through the show floor. And then there's the noise: CES administrators enforce a maximum noise level of 85 dB on the exhibit floor. The rules are looser in the North Hall of the Las Vegas Convention Center, a.k.a. the cool car audio pavilion, where demos can run up to 95 dB during the last hour the floor is open. Talk about a sensory onslaught. We've collected some of the weirdest, wackiest, and intriguing products and events happening at CES, and we're presenting them here.
