Wow, this one is awesome! Took me few seconds before I saw the hidden optical illusion these columns hold. If you still wonder why did I use “sexy” in the title of this post, be sure to double check the photo. The answer is right there. This may be repetitive post to some of you (check the People Trapped inside the Wall illusion), but I couldn’t resist posting this, because it was not so easy to spot it this time. If you like this type of illusion, be sure to check the original Rubin Vase, and the improved versions that popped out afterward.
