From Japan, the world's first nail art that glows when you phone home

Trust the Japanese to take nail art to the next stage of its evolution: LumiDecoNail glows when you pick up your phone, just like E.T. phoning home. It's so kakkoii!

If you thought a finger that glows when you phone home was strictly the preserve of extra-terrestrials, think again: a Japanese firm has unveiled nails that light up when you make a call – it's the first of its kind in the world.
