   Right you are !

The PBM package is included with all of the versions of Linux I've
bought in the last couple of years on CD-ROM (principally Red Hat).

Not exactly GUI based user friendly, but
for weird conversion sequences which can't be handled gracefully
in standard Mac or Win packages it has no equal (and is free to boot!).

In Photoshop, I'd consider the way to do it might be to use the
grayscale displacement function. What this does is to displace
the pixels in an image based on another image - depending on the
value of a pixel in the overlay image, the pixel in the original
image will move a proportionate amount depending on the value of
the overlay pixel (0-255). There might be something similar in
GIMP for Linux based machines (I haven't looked at it closely).

It seems like you could make up a standard sort of gray scale
"mask" of a given size (like 640*480 or 800*600) and just drop
it onto a like sized photo image. Applying this several times
would get you multiiple displacements which you could drop other
image strips into. 

That's about as far as I got with my thinking, though...
