Snap, crackle, pop!

Thanks to Andrew for pointing me to this wonderful electrical rendition of the Doctor Who theme.

The device used here is sometimes known as a "Zeusaphone", because of the, uh, lightning bolts!

According to Wikipedia:

"Zeusaphone, also called a Thoremin, is trademark for a high-frequency, solid state Tesla coil, when its spark discharge is digitally modulated so as to produce musical tones. The high-frequency signal acts in effect as a carrier wave; its frequency is significantly above human-audible sound frequencies, so that digital modulation is able to reproduce a recognizable pitch. The musical tone results directly from the passage of the spark through the air.

This is a variant of the plasma arc loudspeaker, designed for public spectacle and sheer volume rather than fidelity."

If you fancy the musical sparks, you can buy one, here.
