The concept of Mark's Iterations is best explained as a juxtaposition between symmetry and asymmetry. Such patterns are all around us in natural examples like the pine tree. Picture a pine cone, a symmetrically designed object, that can produce from itself an entire tree. The pine tree is not symmetrical, but contains obvious balance. As the branches spread outwards, they produce still more pine cones, that regain their symmetry, and will fall to produce yet another asymmetrical tree. All resulting trees and pine cones contain all the elements of the original, and the juxtaposition continues on into infinity.
This concept is repeated in theoretical mathematics with the images created by fractals. it is from this phenomenon Mark borrowed the name of Iterations.
