I believe it's "Tribe", not "Group".

This conversation has gotten me inspired to play around with the
"Portable Bit Map" (PBM) package, which is widely available on unix
machines.  I think most Linux installations include at least the PBM
headers.  If you're not familiar with it, it is a series of converters
from most common image formats to a "canonical form"; either a bitmap,
greymap or pixmap depending on whether the input image is binary,
greyscale, or color.  There are a bunch of image-manipulation tools that
work on pixmaps included in the package, and then there are output
converters that take a pixmap and convert back to most of the popular
image formats.  It's all command-line oriented, so you need a display
tool like "xv" to see the results.

Anyway, the thought occurred that it would be practially trivial to
write a tool which will take multiple pixmaps and interleave them in any
way desired.  I would have to come up with an interface that would make
it relatively easy to use, say by inputting the pitch of the lenticular
material and letting the program figure out how wide to make the strips,
based on the number of images supplied, the resolution of the printing
device, etc.

I should be able to put something together quickly, as I have written
pixmap utilities before.  However, I have no lenticular material to test
it with, which is a bit of a problem.  Anyone know of a source that
delivers quickly?
