If you've ever used Skype while working from home, chances are you've been wearing pyjama bottoms (or even less) on your lower half, while the clean shirt on your top half has done a passable job of indicating professionalism. No shame there, we've all done it. But no matter how put together you appear, video calling will still rat you out when it comes to your background environment. Laundry left hanging around, questionable wall art, the words 'I hate this project' scrawled on the whiteboard behind you -- all in plain, damning sight of your Skype partner. Until now, that is, as Skype has developed the feature none of us ever knew we needed until it was too late: background blurring.
