Optical Illusion by Escher

Visited the museum Escher in the Palace last saturday and today I received an optical illusion photo they made.

Felt like fun to share it.

Before you get the impression that my GF is a giant and I'm a dwarf, let me set things straight by telling you we are exactly the same size.

My end of the room is 1,5 times higher than her end, thus creating the illusion.

And illusions is exactly what made M.C. Escher a famous artist.

Ps. There's an extra pic too!
