This brick wall looks normal, right?
Just you wait – this is the new ‘white and gold/black and blue dress’ photo.
If you look close enough (or have a quick glance at it again in half an hour), you’ll see that’s it’s not a grey stone wedged between two bricks but it’s 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 “My toddler’s train track is freaking me out right now. What is going on here?!”
He placed two pieces of a train track next to each other – both of which were clearly different sizes – 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 ball… to himself!?
Some Vine users are claiming it’s the work of tricky editing software, but regardless, it’s pretty cool!
