I made the image after I posted, lay off.
Is that what you're trying to do? It doesn't work well on light backgrounds, so try it on a really colorful and dark background to be more effective. That was Liquify: Brush Size = 6, Intensity/Hardness (whatever the hell it's called) 100, with a few strokes all over it. Then feathered 2 pixels, and .5 Gaussion blur.
