    If you look at the Jiggle and Ocean Ripple effects they are both just displacement effects. Jiggle has lots of octaves of noise, while ocean ripple looks to have just one or three to give it that hummocky look.

    The images below are much closer to the effect of the jiggle filter. It's about using a smaller image map with greater dynamic range, I think. The swirly bits are an artifact of the difference clouds effect; using a more raw fBm as might come from Wilbur will most likely get harsher lines.

    The tiliing may be a distraction. The middle row was a 200x200 displacement map. It looks like the important part may be getting the noise at a high enough frequency and dynamic range (get the bumps smaller and with greater blacks and whites).
