In case you hate the office music next time, just throw a paper at it. Just not in front of the boss! :P

Agency republic in London chose to tackle this issue in an R&D project by putting up a poster in the office that says “change the tune” and when you hit it with a piece of paper (or other things handy) an Arduino powered simple piece of hardware in the poster changes the tune on Spotify.
