Tombstone Face Follows You Around

via Mighty Optical Illusions http://www.moillusions.com/2013/04/tombstone-face-follows-you-around.html

Here’s an interesting, yet spooky tombstone my brother stumbled upon while visiting Paris. Based on famous “Hollow Face” illusion (examples can be found here and here), face of the deceased doctor follows you around, as you’re passing-by his final resting place. I can’t imagine how one would react if he encountered this during the night, with full moon shining over the doctor’s face… Feel free to imagine! In case I haven’t fully explained the illusion – Hollow Face appears embossed / convex, even though the shape is actually carved deep into the tombstone…
