That thing in videos where one person is dancing slightly in front of another person is like the visual equivalent to the "chorus" effect in music studio recordings
Basically, in audio recording if you have two similar but slightly different takes, it adds sparkle to the sound, it makes it seem bigger. Similarly with these sorts of tik tok dancers (to me) it has a similar impact, but visually instead of audibly.
Oh hell yeah man. This would be a perfect moment to do some drugs if you’ve got some around. Then look at MC Escher’s art. And crystal structure. And those muslim temples with the crazy-complex geometric ceilings. The concept of target confusion ties into this. This is a really fun, really interesting aspect of the universe and cognition, this repetition, defocusing stuff. The effects a repeating pattern can have on the mind, through the senses. You can induce a spiritual experience by repeated stimulus or action. Like, a zebra’s stripes and an army squad’s jogging chant, and the crystalline structure of metal radio antennas are all utilizing the same mechanism: the de-localization effect of repeated structures. The way elements stop belonging to each piece and start becoming to the whole instead.
