I twirled that chick you gave me (Filter, Distort) and then used Wave (square). Then to soften it I used Watercolor. I used Hue/Saturation to turn it black. Then I took another one of those renders and highlighted a single pixel with the Rectangular Marquee tool. I dragged it out (using ctrl + t) horizontally to fit the whole sig, then I used it again to make it large. Then I used the Splatter filter on that, creating a sort of wavy layer thing. I faded it out, then used Hue/saturation to add the final red color. Then I added the render.
