Second time, focus on the sign in Chinese above. Keep your focus very tightly on that sign. You will not get the effect and will see the installation for what it is. Third time, start off focusing on the sign, then half-way through, switch your eyes to the middle and then go back to the sign. If you’re like me, it’s a weird experience, because the perspective effect is sticky, but the perception of the sign doesn’t match it. Cool stuff. Edit: Fixed the language of the sign. u/SmockBottom is right.
