What do Plato, Dante Alighieri, Guillaume Postel, Raymond Lull, Giovanni Pico della Mirandola, Nicholas of Cusa, Giordano Bruno, Giulio Camillo, Athanasius Kircher, John Wilkins, Francis Lodwick, Leibniz, Ludwik Zamenhof, Bertrand Russell, Ludwig Wittgenstein, Noam Chomsky and Pierre Lévy have all in common? They were all interested (or obsessed) in finding a universal language. While many thinkers have argued about the possible existence of a perfect language, only few have tried to find it.

After examining different models and explanations, Merhi came to the conclusion that a universal language cannot be made out of words but physical elements that can be recognized by anyone, employing the objects certain words denote. For example, he used hundreds of nails to depict the word nail in Korean, or hundreds of magnets to build and show the word magnet in Chinese. Thus, a perfect language functions as a material metalanguage instead of a natural or formal language.

In this case, Merhi used 5 slide projectors and more than 200 slides to depict the word light by means of light in 20+ different languages, including English, Spanish, Portuguese, Danish, Norwegian, German, Dutch, Italian, Swedish, African, Turkish, Finnish, Japanese, Korean, Chinesse, Hebrew, Arabic, Greek, Hindi and Esperanto.
