Stéphane Mallarmé once said that "Everything in the world exists in order to end up as a book. " ECHO is basically a book with a hole inside. It consists 350 pages of last visibility of people who fell and passed away while taking a "selfie".
Like the water that Narcissus looks eternally, book creates a hole to give a chance to create an echo. By reading this book and "looking" to the images, reader has the chance of calling back the self.
Maybe Narcissus was just lonely and maybe he wouldn't choose this way if he had heard Echo's voice. Because after all as Susan Sontag said "Today everything exists to end in a photograph.
" Echo takes its information from Wikipedias "Selfie related Injuries and Deaths" link.
