Personally, I'm starting to think more about the CMB as a fractal image. I recall that it has been confirmed that it it does indeed have a calculable fractal dimension within the appropriate range. If this is the case, then both ordered regular patterns would be expected amongst the seeming remainder of chaotic image ('caused' by nothing more than the intrinsic behaviours of rapidly expanding, interacting radiation ).
Coming from this perspective, it is not surprising that CMB radiation could self-organise to form patterns which we might normally recognise and relate to other ways such patterns may form elsewhere in nature (like from rapid expansion of patterns formed in minute discontinuities in a fluid medium).
Whether or the CMB patterns are actually caused in the same way theorised by Penrose et al, is highly debatable and not necessarily likely. (This is a nice way of saying that the pattern is more likely to be in the eye of the beholder .. much like tea-leaf gazing to tell the future).
The Penrose et al papers are regarded with much scepticism within the scientific community. See the
'counter arguments' here.
