Sometimes when I squint hard and rub my eyes, it's the same or a very similar yet milder version of the patterns I've seen while consuming serotonin receptor agonists, specifically those of the prototypical 'psychedelic' variety. In fact, I noticed this similarity when squinting last night a couple weeks after experimenting.

They resemble the images in the upper right and lower left, generated in the model - hexagonal, not the stripes, nor converging toward some central point.
