Spooky Scary Skeletons performed on three musical tesla coils by Franzoli Electronics
From Franzoli Electronics:
For those who did not understand what is going on this video, here’s a brief explanation: The main loud music really comes from the tesla coil sparks. They are literally playing the music due to the programmed phase, pulse width and firing frequency! So, there are no speakers, no audio / video special effects. It looks even better in person and sounds almost the same, just louder than people expect!
