english: So I'm going to show you some ways that we can violate your expectations. First of all, I want to show you the particular illusion here. I want you first of all when it pops up on the screen to notice that the two holes are perpendicular to each other. These are all perceptual tricks. These are real objects that I'm going to show you. Now I'm going to show you how it is done. I've looped the film here so you can get a very interesting experience. I want you to see how this illusion is constructed, and it's going to rotate so you see that it's inside out. Now watch, as it rotates back, how quickly your perception snaps. OK now.
non_english: Pokazaću vam nekoliko načina na koje se očekivanja mogu narušiti. Prvo ću vam pokazati jednu posebnu iluziju. Želim da, kao prvo, kada se ovo pojavi na ekranu, uočite da su dva otvora u normalnom položaju, pod 90 stepeni. Ovo su sve perceptivne iluzije. Ovo su stvarni predmeti koje ću vam pokazati. Pokazaću vam sada kako je to urađeno. Vratio sam malo film da biste doživeli jedno zanimljivo iskustvo. Želim da vidite kako je stvorena ova iluzija, a ona će se okretati i videćete njenu unutrašnjost. Pazite sad, dok se ona rotira unatrag, kako se vaša percepcija brzo menja.
