Tomorrow Transformed explores innovative approaches and opportunities available in business and society through technology.
(CNN)Each year tech junkies from around the world gather in Las Vegas for International CES, the Consumer Electronics Show where innovators come to show off their latest prototypes, preview products and announce new releases.
Although the show is over 40 years old, this year's event, held from January 6 - 9, saw some of the most futuristic products ever, from driverless vehicles to a revolutionary battery which, according to its makers, could let you fully charge a cell phone in minutes.
Here is some of the coolest tech from the show.
1. Mercedes-Benz unveiled its driverless vehicle.
Although the F 015 Luxury in Motion is just a concept car at the moment, the vehicle shows just how different Mercedes thinks our driving experience will be in the future with an automated driving option and luxury "mobile living space" interior.
"Quality time in private space will be the true luxury goods in the future," said Dieter Zetsche, head of Mercedes-Benz cars in his CES keynote speech.
2. People controlled objects with a wave of the hand.
The latest version of Ring, by Logbar, was unveiled at CES 2015. The cloud control device allows you to do things such as play music from your phone or close curtains using gestures programmed into a smart phone app.
The $269.99 device was named as a 2015 CES Innovation Awards Honoree in November 2014.

3. A robotic arm played beer pong.
Empire Robotic's Versaball is filled with a "sand like material." When air is pumped into the ball it softens, molding around an object, and then when air is removed, the green ball hardens and grips objects from bricks to ping pong balls.
