That's crazy. I feel dumb for initial thinking it was somehow doing eye tracking to achieve this, despite having no such hardware installed.
I would be curious to see a similar thing that includes flashing. Anecdotally, my peripheral vision seems to be highly sensitive to flashing/strobing even if it is evidently poor at seeing fine details. Make me think compression in the time domain (e.g. reducing frame rate) will be less effective. But I wonder if the flashing would "wake up" the peripheral vision to changes it can't normally detect.
Itβs normal to be "more sensitive" to brightness differences in the peripheral areas compared to the fovea. The fovea has more color receptors, in the other areas, there are comparatively more monochromatic receptors (brightness). The general density of the fovea is also much larger.

Not sure what the random jab at Linus is about.
