Tesla coils dance spritely across stage

Well, not exactly. But in what is possibly the most wonderful display of dorkese I have ever seen, two self-described "tech coilers" have built solid-state tesla coil systems that lend themselves to audio modulation. The result? Tesla Coils that perform the Nutcracker's Dance of the Sugar Plum Fairy. Read more about how they did it here. (Thanks, Michael, for sending me the Youtube link.)
