if this is the case, in theory we could generate those same visuals by identifying the neural activation patterns of the vortex when your eyes are rubbed, and simulating the effect they should have on your perceptive plane
unfortunately this is basically impossible
at least, w/o smth close to full-brain emulation
w/ our current methods of non-invasive brain activity detection, we can't get anything close to a high-enough resolution model to make this happen
if we could fully reconstruct & simulate the visual correct itself, then perhaps
