Are there any other options for doing this, perhaps within ccp4 and/or phenix? I once saw someone give a presentation and they had a little video that showed a three dimensional section of the reciprocal lattice rocking back and forth, which was really cool. I liked this because I felt like it gave a much more holistic representation as opposed to viewing a bunch of individual sections. I don't know if there is an easy way to do this, or if this person somehow managed to create this 3D depiction from a series of sections.

"hklview" is the classic ccp4 program for viewing 2D slices, but there
is a much more modern version on CCP4's "prerelease software" site
called "ViewHKL".  For some reason they decided not to release it with
ccp4 6.2, but it's very nice.

For a 3D view of reciprocal space, try phenix.data_viewer, also a
button in the main GUI.  (It does 2D display too - this may be more
useful than 3D for visualizing some pathologies like translational
NCS.)  It's still under development - you'll need a recent nightly
build.  There's no animation support, but now that you've mentioned
