As a guest speaker at the PDP Conference in September 2020 in Novi Sad, Serbia, I decided to leave a mark in the city. I wanted to paint a mural, but didn’t know what to write. So I asked my Instagram followers to send me messages. It could have been anything. It was so not about the content. At the end a linguistic mess arose: English, Serbian, Georgian, German, Mandarin, Arabic, Norwegian, Turkish, Ukrainian, Dutch and many more. It looks like senseless schizophrenic tagging from those mysterious and a bit scary taggers that exist in every city.
