It is a fairly simple base, actually. A scry transform and a bipolar transform, and then you add a linked foci to the bipolar, and scale the foci to pi/2. Then you have to start moving transforms around and/or adding other post transforms in order to get patterns to show. The idea is that scry maps everything to a circle at origin, and the foci will map the bipolar to the area surrounding that circle. So foci and scry are visible, and if you alter one of them you should probably alter the other in a similar way.
If you want, I can ask Travis if it is okay to send you the base params he sent me (which I actually only looked at after I had already built this from his description ).
