nice idea, which can be very usefull if you like to listen to music on your desk, if you are not at your desk but outside / on the road, it can be an idea where your friends are on purpose clapping at it, you lose it, it stops working, especially if its vulnerable. does it pay everything when its in your back and picks up some stuff? it needs to be connected tot the internet aswel, also bluetooth or priorly wifi? a soundbox is now a payment device.. it could work if its very decent else I see mmore cons than pro's in it but it is a nice device to support a facility and maybe (if it works ) enhances more community voting but I doubt the usefulness slightly more
