Those are called Shepard tones: http://en.wikipedia.org/wiki/Shepard_tone
Trivia: one was used in the "endless stairway" part of the Mario 64 video
game, to good effect :)

It does. It works best if you use a dense set of notes moving
over a range of several octaves. With just one or a few the
fade-ins/outs at the start/end are quite apparent.

I once made such a thing, it's fairly easy using Csound
or similar. You just need a note that moves up (or down)
at a constant speed, with a fade-in at the start and a
fade-out at the end, then make it loop, then start a large
number of these at different positions in the cycle.
