These circles are stationary
Thanks I hate it.
*sigh* all power to hypnotoad.
Checked with a ruler and took screenshots - the circles are completely stationary. The effect is also not generated by the arrows, rather by the oscillating color.
The rings have 1px wide borders that oscillate out of phase with their interiors, and your eyes perceive the phase shifted borders as moving edges. It’s really neat, our optic nerves have specific hardware for edge detection and this gif fools it!
Also if I look away from the gif and stare at a spot, the gif looks really trippy in my peripheral vision. A++
