I'm totally fascinated by optical illusions - our brains are so complex, yet it can be tricked in so many ways because often, what we see is not what we think it IS.
While procrastinating and browsing the internet today (yes, I was supposed to write an essay instead...) I found an article featuring these awesome pictures that are almost like optical illusions.
The pictures are not my own! - Source
Isn't it crazy to think that nature created all of this, just by chance?!
It's so awesome that photographers were able to capture that!
