Silhouette

The sun falls below the Aegean Sea while silhouettes of the traditional windmills are visible while people enjoy the food or a drink

In 2003 a Japanese web designer called Nobuyuki Kayahara created a spinning dancer, also known as the silhouette illusion, which apparently tells you whether your are a person who uses the right part of his brain (creative), or the left part (logical). If you see the dancer spinning clockwise you are logical, while if you see her spinning counter-clockwise your are a creative person.
