"Drip" & "Emotor" Reaction

Being musically inclined myself, I particularly was fascinated with the "Drip" video. The whole concept of making music with rain drops is something that I never seen before. The Emotor video was also intriguing but I really didn't understand the concept. Motorizing facial expressions that normally people wouldn't be able to do seem a bit pointless. Nevertheless, I think that Tim Hawkinson has unique concepts that he's pursuing.
