So I assign a random variable, maybe controlled by a slider, in the first line giving a fractional value, and then use that variable in the wiggle expression on the second line. Thank you.

Thanks for the link to Dan’s site, I’ll be sure to check it out. Wiggle will not work in it’s pure form as I would like the opacity to change slowly, over a couple of seconds even. Think of a ghostly image slowing fading in and out of view.
