This is how to make something like the style used in Chainlink, among other of my pieces.

Open Apophysis, and go to Options->Options
Under the random tab put this:

img:symmetry

The main thing you want to do is change the symmetry because it will make it spiraly. Basicly anything higher than 100 for order will be fine.

Now press CTRL+B to create a new batch with those settings. Then mess around for a bit and when you're done use something like this for your render settings:

img:render settings

Really the thing you want to focus on is quality. Rendering at 1500 should be fine.

basicly all I do is duplicate the layers, make the opactiy about 65 on the top and then do a 2.0 gaussian blur and just change to focus it
