Picture this, we're all busy away working in the office, headphones on concentrating on catching up with the hundreds of emails over the holidays. Trying to get the attention of our intern who has his headphones turned up a bit too loud. We shout over the headphones, to pause the music he puts his hand up to the camera and the music stops.

Looking rather confused, we asked him how his Macbook Pro recognised the hand signal and paused the music. We're thinking it's a Mac thing, and we're excluded as we are part of the PC crowd. From there he shows us additional commands to skip forwards and backwards. Eventually we beat the truth out of him and he tells us its called Flutter.

So if you want to look particularly flash, impress your co-workers or your friends then I recommend you head over to Flutter and install the app.
