Tesla Coils are a special type of transformer originally intended to broadcast electrical power without the use of wires.  These days they're primarily used for special effects in TV and movies, electrical testing (why wait for lightning to strike? Make your own!) and plain old mad-scientist style geeky fun.

Instructables has a couple of excellent tutorials on building the Basic Spark Gap Tesla Coil, and a more advanced Solid State Tesla Coil that can be modulated to play music.
