It sounds like a nice amusement or thrill for the people that are actually wating till a train has passed... It is a nice try, but it won't work.... In case you are in a hurry or suffer from a light impacientness, you won't stop and stay to watch the near misses. And even if such a person sees some of them, he will come to the conclusion that everyone got away unharmed... I suppose impacient or people in a hurry won't take the time to watch the videos of the QR-codes. People crossing rails in front of approaching trains don't caclulate the odds and prices, just like people smoking and playing the lottery.

It must be the elephant, as elephants have bigger heads. and are also the larger animal, it would easily be possible for an Elephant head to cover a bull's head, while it would be much more difficlult for a bull to coer an elephant't head... ;-) But the illusion is quite nice, showing that the beholder tends to see what he wants to see! I think the artist had much fun developing this illusion.

"Battenberg cake" on steroids...

You pay for big brohter for riding shotgun. But Alexa, Cortana, Bixbi,Siri and so on are alrady spying on us with much more accuracy...

Shut up and take my money!

Now i see why it is called the "blue planet".

The three story windows shutter would be so cool if you could open and close them from each of the windows! But most of them seem not even movable.

This is just sad.

The Jurassic Park Poster is the best.

Ah, just a red herring for red herrings's sake.
