I've run a small render farm back when I did forensic animations -- but
you don't have to have the computers connected for a render farm. But
yeah, if I have 100 images and want to do ffts on all of them, I can
run
scripts on five machines that do 20 each. I'd like to see if a "real"
cluster would improve stuff. In addition, some of the software I've
used supports real parallelism.

How do you define "real cluster"?
Something that I can take *one* program compiled for parallelization
that will distribute the processing among machines, as compared to
running multiple invocations of a program on different machine, each
chewing on a different dataset.
For instance, a render farm where I run 15 instances of Maya or Blender
on 15 machines, each rendering a different set of frames to be later
combined for an animation isn't a "real cluster" to me. Running one
instance of Maya or Blender to use the memory and processing of all 15
machines would be a "real cluster" for me -- assuming a parallel version
of Maya or Blender that could do that, of course.

I think OpenMosix tried to do this but went defunct quite some time ago.
LinuxMPI seems to have taken over the source code, but I am not sure it
does what you want.
In short, I don't know if there is anything that can sum the
computational power of multiple systems and transparently make it look
like a single super fast machine.
