It is always surprising

very cool illusions.. Are the shadow one's real or am I just a sucker??

I don't think the shadows are real. In the 1st one I tried to find the holes in the garbage that corresponds to the space between the silhouette's necks and could not find it.

the elevator would make me shit myself.

A lot of these are cool but hardly any are actually optical illusions. An optical illusion is, in example, like when you're driving in a car looking at the road and you stop, then you look at the road and it seems like it's still moving. That is a trick your eye does to your brain.... not just a cool painting on bus doors or elevator floors.

the silhouette one is real if you believe it's real. i believe.

I coulnd't use that elevator..

Scary. Shadows well done.
