This brick wall looks normal, right?
Just you wait โ this is the new โwhite and gold/black and blue dressโ photo.
If you look close enough (or have a quick glance at it again in half an hour), youโll see thatโs itโs not a grey stone wedged between two bricks but itโs actually a Cuban cigar sticking directly out from the wall.
Have you spotted it yet? Once you see it you will never un-see it!

Here are a few more tricky illusions, like this baffling video posted by Twitter user Marc Blank-Settle.
It read the caption โMy toddlerโs train track is freaking me out right now. What is going on here?!โ
He placed two pieces of a train track next to each other โ both of which were clearly different sizes โ but when he placed the longer one on top, they are exactly the same size.
Mind-blowing!
Another unexplained video is of Kevin Parry filming himself in front of a mirror and bouncing a ballโฆ to himself!?
Some Vine users are claiming itโs the work of tricky editing software, but regardless, itโs pretty cool!
