The artist duo Hörner/Antlfinger has been undertaking time travel experiments which center on the process of imagination with different participants across multiple countries since 2005. Under guidance of the degree certified psychiatrist Assad Zahran, the time travellers will go in a light trance and imagine the city of Düsseldorf as it was, is or will be in the past, present and future. The mental images made on this journey can be captured in drawings or notes and will subsequently be discussed with the fellow travellers. At the group exhibit "Planet B - 100 Ideas for a New World" (2016) the artist duo Hörner/Antlfinger have presented their media art installation "Back to the Future, Forward to the Past. Three Time Travel Experiments".
