I've never really done anything with media, just pigments and textures. I'm
wondering if there's a way to create a lightning-looking effect.
Any ideas?

media using a crackle or marble pattern might do well. Several people that I
know of have made lightning, not all the same way though. Using a recursion of
objects (cylinders) in a CSG is one way.
I think if you were to use a thin box though having a marble media in it that
it should look pretty good. Someone's probably done that before too. Here's
how:
box {-1,1 scale <10,10,0.1> // thin z plane box
pigment {rgbf 1}
interior {
media {emission 1 // self illuminate
density {marble density_map { // pattern
[.025 rgb 5] [.03 rgb 0] // fine line
} turbulence .3 scale 3 } // stir it up
} }
translate 3*z // move back from camera
hollow
}
camera // must look perpendicular to box
{
location -3*z
look_at 0
}
Not perfect, but something to go by.

Not exactly what I had in mind, but by using multiple objects, that'll
actually probably allow me greater control over where it goes and how it's
aligned. Thanks!

Bob's mind is slipping on us :) He forgot to mention the lightning include

No, not this time anyway. I was going on the assumption a self-made lightning
was the goal so I was only showing one way it could be done. I did hint at the
fact many other people have already done some form it too.
Any other time though, yes, my mind is slipping and sliding away.
