Want to see the Genius Loci? Focus on the roofs of Portoroz and piran.
Every city has its own Genius Loci, the Spirit of the Place. But what is it? How it looks like?
To reveal it you just have to make your eyes unfocused and then focused in 10-15 seconds. As the result you will see a stereographic image, which is based on The Magic Eye Stereogram Principle (http://www.magiceye.com/). Hint: this poster reveals you a drum -- a logo of Golden Drum festival, which those two cities are famous for.
