The Fold to Infinity

If Deleuze's Le pli: Leibniz et la baroque (1991) made no reference at all to fractals, I could understand it as an attempt to limit the concept of 'the fold' to a Leibnizian, Baroque context and idiom. If he referred throughout to fractals I could understand it better: because surely fractals most perfectly emobody the fold to infinity ('the Baroque trait twists and turns its folds, pushing them to infinity, fold over fold, one upon the other. The Baroque fold unfurls all the way to infinity' [3]). The puzzling thing is that Deleuze does neither: he mentions Mandlebrot once ('Mandlebrot's fractal dimension as a fractional or irrational number, a nondimension; an interdimension' 17) and not again. Which in turn makes me wonder: does the fact that this books makes me think of fractals mean that I just haven't understood this book?
