For those who clicked onto this cube illusion, you can see that sometimes the illusion shows six cubes and sometimes it shows seven cubes. This is a very important illusion to me. When I was 11 years old, I wrote a term paper on psychology. I had come across this illusion and it so intrigued me that I decided to become a psychologist from that point on. Now you know the story about why I took the career path I did.
