The pink dot thing is trippy...
It works by exhausting your color receptors. Take the sky for example, it is orangey in the original image. After viewing orange for a while, it drains a large amount of red and a medium amount of green, leaving blue with a tinge of green which is what the sky looks like. The opposite of pink in the case of the moving pink dots is green. Not only do you eyes have color receptors but they also have motion receptors. So watching something spiraling inward for a while will cause stationary objects to appear like they're expanding outward for similar reasons.
As for what causes exhaustion, I'm not entirely sure but I believe it has to do with the way that sensations tend to follow a decay curve (intuitive reason is that if something's going to be in your field of view for a while, it shouldn't be alerting your brain the whole time, so after it notices it, it gradually stops being as noticeable).
