How about:
pigment{gradiant x
colour_map{
[0.0 colour White]
[0.3 colour Black]
[0.6 colour White]
[1.0 colour Black]
}
scale 0.5
turbulence 0.5
translate x*100 // don't want to see the bit that's
// at x*zero
}
Havn't checked the spelling so things like turbulence and gradient
mibht be wrong, (I always get them wrong).

You spelled color wrong in six places :)

No colour is was the correct spelling but there was a big mistake
code wise, which came to me while walking in the woods this fine
evening.
pigment{gradiant x
colour_map{
[0.0 colour White]
[0.25 colour White]
[0.25 colour Black]
[0.5 colour Black]
[0.5 colour White]
[0.75 colour White]
[0.75 colour Black]
[1.0 colour Black]
}
scale 0.5
turbulence 0.5
translate x*100 // don't want to see the bit that's
// at x*zero
}
This is the corrected code, I'll let you work out what the big
mistake was in the earlier version that I posted.

Why not
{
[ 0 White ]
[1/2 White ]
[1/2 Black ]
[ 1 Black ]
}
?

Try again ... it's spelled gradient. Tsk, tsk, tsk! ;-) Nice
Zebrapigment, btw.

Don't know, I always prefer to have two instances of each colour,
just one of my idiosyncracies I suppose.

While you're at it, why not:
{
[ 1/2 White ]
[ 1/2 Black ]
}
? :-)

I didn't know that would work.
OK this looks good for zebra stripes. The camera is looking at a y plane.
pigment{
gradient x
turbulence 0.3
colour_map{
[1/2 White]
[1/2 Black]
}
scale <1,1,8>
}
