circular intricacy

I began to look at how the aggregation of intersecting, tangential, rotated and scaled circles can create new continuous curves that could start to define a space.  Below are a couple of tests.  The first was looking at the difference of un-intricate to the extremely intricate on the other side, and how at a given moment they could intersect.  The second was looking at very intricate curves to create varied types of enclosure; from more open to more enclosed.  In both cases the introduction of a 3D curve shifts the intricacy.
