	That's pretty much it - I use an old neon sign transformer,
	although any transformer with about 7500 VAC will work.  Make
	the "ladder" out of #12 or so copper wire, adjust the shape
	of the "V" so an arc starts at the bottom and travels to the
	top.  For a very large "ladder", you can suppport the wire every
	50 cm or so with insulators.  Be careful; this can kill you. . .
