This is one of those things that makes you think "WTF!?" At first look, it seems completely impossible, you can go over it and just don't understand how it is done, yet you see it is there, in front of your eyes. In this short video i have explained how this illusion is achieved and why we (humans) do not see it at first.

In case you are wondering, it took me about 1 minute to figure this out for the first time, just had to follow the lines. Photoshop edit is to visualize the illusion and show you the details.
