Having a good/bad day and want the world to know it? You need the Sky Neon Sign handset.
Except you’ll need to be in Korea to buy one. If you are, you get a phone with 49 LEDs on the front panel to show off images and animations representing your mood. As well as that, there’s a 2MP camera, MP3 player, dictionary and text viewer.
Sold in white, sky blue, pink and black variations, it sells from the equivalent of £197.
