Diary 2020, also acting as a handy calendar and planner, contains the works and drawings of our residents, short texts from the collaborators and guests of the Ujazdowski Castle Centre for Contemporary Art as well as information about the Castle's programme and activities. The leading theme of this edition is the future of our planet – what it could mean for the individual and for society. The text part includes a mini essay on the topic of time by Maja Demska, speculations for the year 2050 by Joanna Grabski and Krzysztof Gutfrański, and a recipe for Mohammad Saleh's biomimicry.
