@ApostateEnglishman@mastodon.world @Pikestreet@ohai.social @conchoid@mastodon.gamedev.place @Danpiker@mathstodon.xyz did you, as I did, try to experience it during an insomnia at 4 am WHILE THE BLUE LIGHT FILTER OF YOUR PHONE’S SCREEN IS ON ? Honestly I realized it when by day the illusion worked for me contrary to the middle of the night. In French we have a saying that at night every cats are gray, similarly, at night, every dots are purple.
