    The original animation, modularized with sliders, was first "exhibited" on [[https://radiostudent.si/kultura/humanistika/delo-in-tehnologija][october 6th 2017]] in [[http://atrog.org/prostori/modri-kot][Modri kot]], a beautiful space for performance that used to be on the side of the [[https://tovarna.org/][autonomous factory Rog]] in Ljubljana, which was evicted by force on january 19th 2021 by the municipality to pave way for future gentrification.
    Special thanks to Zala and Lio for hosting me during early development and Tisa Neža for curating the first performance.
