Just something I made today. This uses the Black Winter Moonlight gradient in my gradient pack [link] and a modified spiral batch script from the one you get with Apophysis. I lightened the background colour from the default black you get and this seemed to give it a slightly more transparant look than it did with plain black. The black line you can see however is something from the script and while the repeats of it are less obvious, there was nothing I could do to remove it unless I exploded the spiral out and lost the whole shape that I wanted.
