Barber's Pole Pattern by Roland Kuit
You can find a tutorial on how to create a Barber's Pole on Roland Kuit's site here.
"A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.
It has been described as a "sonic barber's pole". The acoustical illusion can be constructed by creating a series of overlapping ascending or descending scales.***"
Roland Kuit brought us the Roland Kuit's Laboratory of Patching previously posted here.
Update: one more demo & image of the patch:
