2: DJ

A few years ago, I visited a friend and he had a remote control for all the lights in his living room. I spent some playing with it and at the end I recorded a video where I could "control" the lights only with my arms. As a background it was playing "The Final Countdown" by Europe. Some months ago, a friend invited to play Just Dance. Now, instead of dance following the music, it's the music that it's following you.
