Barnaby Dixon (previously at Neatorama) puts his unique hand puppet artistry to work. This fluorescent puppet he calls "creepy face" has a tiny screen for a mouth that shows Dixon's vocal work in real time. The song is his version of "Nightcall" by Kavinsky.
You may notice that the puppet is in a similar part of the screen whenever the vocoder is heard, shifting his weight slightly between phrases. This is because I'm using my thumb to play the chords :D
