The Rolly was first announced in 2007. It's a Bluetooth speaker, an MP3 player, and bizarrely a sort of robot. The Rolly has two arms, two legs and two wheels that can either move under the user's commands or automatically wiggle in time to the music.
The Xperia Eye concept gadget was displayed at the 2016 Mobile World Congress. The wearable camera uses a wide-angle lens to capture the action without needing to worry about framing or getting the camera out.
