This is totally – like way – cool, dude. Performed by the aptly-named ArcAttack! group, the film clip below shows some Tesla Coils taking part in a rendition in their own unique manner of the Doctor Who theme tune.
An underappreciated quality of the lighting generating coils is their adeptness in making music. It so happens that bolts fired by the coils create "crisply distorted" square waves that don’t sound too different from synthesizers.
ArcAttack! was founded to utilise this quality in a performance environment, coupling a DJ system with the Tesla coils.
