I downloaded and played back at higher speeds as well after your suggestion. Using the same technique to view the 3D image in those "posters from the 90s", I could make out the messages too.
Persistence of vision type of tricks/effects have always been a favorite of mine. Even without LSD, I still enjoy finding ways to "trip" the mind. I have a ceiling fan with dark tone blades hanging from a white ceiling. When laying down in bed, I can stare at the ceiling fan for a couple of seconds, and then when I close my eyes, I still "see" the ceiling fan but in a negative view where the ceiling is now dark and the blades are light color. Cheap LEDs and fluorescent lights with cheap ballasts also cause me to see weird flickering when using averted vision or by turning my head back and forth in a rapid manner.
Maybe it's because of the training my brain has undergone from using psychedelics, but I've tried to get other people that have never used psychedelics to see the same things without success.
